• Starting with V7.1.1, the server will immediately refresh the data on server tables used by the OC
Benefit
• Allows the OC to display more up to date information without waiting for status refresh interval
Server Support
• Applied to all status monitor table( TSMGUI_nnnn_GRID tables )
• Currently does not apply to Alerts table – it has it’s own update and refresh handling
• Does not apply to TSMGUI_STATUS_DATA
• Table used by OC “Overview” page
• Refresh is still done only at status refresh interval due to constant changing nature of the data
• Full refresh of data in all OC related tables ( TSMGUI_xxxx_xxxx) are done at status refresh
• No auto refresh if status refresh interval is set to 3 minutes or less
• Avoids conflict between the two refresh cycles
• There’s minimal delay, for example if a node is added to the schedule in the OC
• Update is made on the server; Server pushes the update to the OC; OC table gets refreshed
• Status Retention is changed from 48 hours to 24 hours

TSM 7.1.1 Performance Enhancements – Node Replication’s Reconciliation
Prior to TSM 7.1.1, replication has always done a reconcile
●
–
Compares complete list of files between the source and target server
–
Used to synchronize the source and target servers / Makes target server look just like the source server
Reconcile in TSM 7.1.1- Examines entire list of files in a file space (much like pre 7.1.1)
●
–
Used during the initial replication between 7.1.1 servers
●
Once reconcile completes, change tracking processing takes over during the next replication
–
Automatically runs following a database restore on the source or target server
–
Can run manually using REPLICATE NODE FORCERECONCILE=NO|YES
• Synchronize source/targert files - used like an audit
• Resynchronize source/target files if the db is regressed (other than DSMSERV RESTORE DB)
Restartable – remembers where it left off if cancelled or after some catastrophic server event
–
Change Tracking in TSM 7.1.1 eliminates need to query target server for its list of files
●
–
New and change files are assigned a change identifier: when it’s stored & when meta data is updated
–
Replication only processes files with a change identifier – incremental replication
–
Replication picks up where the last replication left off
–
Improves performance for fs with lots of files
New Replication rule that enables replication based upon Domain
●
–
34
In addition to current replication by Server, Node and Filespace
TSM 7.1.1 - Node Replication with Dissimilar Policies
Description:
Decouple target from source server policy, allowing target server to manage replicated files via its own policy
●
Benefits:
Maintain more or fewer versions of replicated backup files between the source and target replication servers
Retain replicated archive files for more or less time on the target replication server
If fewer versions of files are kept or retained for less time on the target server, the amount of target server
storage required can be reduced
●
●
●
Server Support:
Different policy for retention time & number versions can exist on primary & target server
●
–
–
35
On source server first run VALIDATE REPLPOLICY
●
Default is to disable dissimilar policies
●
If disabled, the serves will act as they do today and honor the source server’s policy
On source server SET DISSIMILARPOLICIES server on
●
Once enabled, target server is notified during the next replication
●
VEREXIST, VERDELETED, RETEXTRA, RETONLY, RETVER, RETMIN – will impact what is kept
●
Expiration then runs independently on each server – target server runs expiration
TSM 7.1.1 - Node Replication with Dissimilar Policies
Backup data:
VEREXIST, VERDEL, RETONLY, RETEXTRA control when a backup is deleted
Archive Data: Only RETVER controls the length of time a file is retained for
Space Management Data: Retains the same behavior with or without dissimilar policies enabled
VALIDATE REPLPOLICY <server>
•
Must be ran prior to enabling dissimilar policies
•
Displays differences in policy settings for all nodes that exist on both source and target servers
•
Can be used to validate policy settings are correct, or to debug policy related issues
•
If no server is specified, defaults to current replication target server
SET DISSIMILARPOLICIES <server> <on|off>
•
•
Issued on source server to enable dissimilar policies for a specific target server
Must run VALIDATE REPLPOLICY for the given target server before this can be enabled
QUERY REPLSERVER
●
New field added to tell you if Dissimilar Policies is enabled for target replication server or not
Rebinding of Files on the Target Replication Server
36
●
In 7.1.0 <=, files bound to STANDARD on target server if the mgmtclass didn’t exist at the time of replication
•
With Dissimilar Policies, the mgmtclass that a file is bound to on the target server is now important
•
During Reconcile Replication, files will be rebound to the correct mgmtclass if it exists on the target server
•
Done at server level the first time a replication is run after upgrading to 7.1.1
•
Done at node level when REPLICATE NODE forcereconcile=yes
TSM 7.1.1 - Node Replication with Dissimilar Policies
Changes for Expiration
• Source server
•
If dissimilar policies enabled, source server holds onto a file until it has been replicated to the target
•
•
•
Files that have not yet been replicated, must be replicated before they can expire on the source
Files that have been updated ( active → inactive or inactive → expire immediately ) must be replicated (updated)
before they can expire
Bypass this requirement temporarily by updating the node or filespace replication rule to NONE
• Target Server
• All files are now deleted by expiration on the target server
•
Replication process no longer directly deletes files, instead deferred until expiration processing on the target server
•
The exceptions are group data and hsm data: These are still deleted during replication processing
• If dissimilar Policies is enabled, the targets policy take affect as data is ingested into the server
•
This is exactly the same way a client backup is handled
•
As a file comes in, if there is an extra version, it is set to be expired
• If dissimilar Policies is not enabled, the data's state is copied from the source serve
•
If it is active on the source, it will be active on the target
•
If it is inactive on the source, it will be inactive on the target
• When expiration runs, it will delete files as it always has
37
•
Files that are expired will be removed whether dissimilar policies is on or off
•
Dissimilar Policies just dictates how files are set to expired during the ingest of the data
•
ARCHIVE data that has passed its retention data is only expired on the target if dissimilar policies is enabled
TSM 7.1.1 - Node Replication with Recovery of Damaged Files
Description: Retrieve files that have been damaged on the source server from replication target server
Benefit: Assist with local recovery of files that have been damaged on the source server
•
•
Replaces damaged files with good copies that have been replicated
Includes files on volumes that have been updated as destroyed
Scenario:
1)
2)
3)
Server A replicates data to Server B
Storage pool volume or files on Server A is lost or data is otherwise inaccessible
Storage pool volume or files is restored from Server B to Server A
Server Support:



38
Must enable: SET replrecoverdamaged on
Additional step in replication process, if source server has damaged files in a file space being replicated
• Notifies the target server to resend them at the end of the replication
• When source replication ends, the target would start process to resend the damaged files
• Damaged files are deleted and replaced with new copies, retaining original insertion date
New parameter on REPLICATE NODE command: RECOVERDAMAGED=YES|NO|ONLY
• RECOVERDAMAGED=ONLY will not do replication, it will only recover damaged files
TSM 7.1.1 - Node Replication with Recovery of Damaged Files
•
New column in Replicated_Objects tracks damaged files
•
•
•
•
Valid values are currently 0 (not damaged) and 1 (damaged on source)
Worker thread periodically re-synchronizes the Damaged column
Thread wakes every 30 mins, only syncs if count of damaged changed
Source server initiates recovery, target server controls
•
At the end of a replication process, the source server will decide if a recovery is needed
•
If so, it will build up the recovery command and send it to the target for processing
•
Target starts modified replication process & corresponding replication recovery process on the source
•
The source & target will talk, with the target requesting damaged files and the source supplying them
• Grouped objects
•
Requires special consideration, object ID cannot be reused
•
Groups are repaired with the new object IDs during recovery
• Deduplication
•
39
Reuses existing replication code to only send needed chunks
TSM 7.1.1 - Node Replication with Recovery of Damaged Files
Does not seek out damage
•
•
Server must encounter damage through data movement (reclamation, client restore, move data, etc.)
Or volume must be marked as destroyed
Deduplication (Largest area of limitation)
•
•
When a base chunk becomes damaged, links to it are not automatically made invalid
Example:
• Node Bob backs up coolstuff.txt, which is split into 5 base chunks, stored on VOLA.BFS
• Node Jason backs up files, which links to all five chunks created by coolstuff.txt, stored on VOLB.BFS
• Administrator replicates node Jason, but not Bob
• Administrator marks VOLA.BFS as destroyed
• Replication recovery will not recover node Jason's damaged files
• Solution - run audit VOLB.BFS
• Audit Volume marks all damaged files on the volume, if the base chunks are damaged
• Client restore marks individual files as damaged, but not all files sharing the same chunks
• What if Node Bob was replicated?
• No additional action is necessary
• Chunks come back, links repaired throughout pool
Relinking limitations
•
•
•
One relink thread for all replication recovery requests
If server crashed/restarted, potential for many outstanding invalid links
Solution, run Audit Volume on all volumes potentially with replaced damaged chunks & run Validate Extents
Update Volume
•
•
If server crashes/restarted during an outstanding update, not all bitfiles marked damaged
Solution: Mark volume read-only, then back again to damaged

TSM 7.1.1 256-bit EAS Backup Archive API encryption
TSM now supports 3 algorithms of encryption
●
–
AES-128
–
DES-56
–
AES-256 (NEW)
TSM 7.1.1 introduced AES-256
●
–
Backup-Archive Client , API and DPs that use the API
–
Use ENCRYPTIONTYPE AES256 in dsm.opt or dsm.sys
●
41
Then rebackup already backed up and encrypted items
–
Data deduplication is not supported with encryption
–
“query backup” shows encryption being used
–
Client GUI will have new option
Meet National Standards
TSM 7.1.1 and FCM Conformance to NIST SP800-131a
Description:
Special Publication 800-131a
•
Information security standard of the National Institute of Standards and Technology (NIST)
•
Requires longer key lengths and stronger cryptography than other standards
•
Ability to enforce use of TLS 1.2 or higher when SSL is used
Benefit:
Stronger cryptography when using SSL
Server Support:
•
Product options to require use of TLS 1.2 or higher ( when SSL is in use )
•
•
42
Server / Storage agent option: SSLTLS12
•
Default is No (specifies that the server uses TLS 1.1 for SSL sessions)
•
YES (causes the server and storage agent to prefer TLS 1.2 )
•
Client, server & storage agent check that the session has been setup with protocol TLS 1.2 or higher
•
They will break the connection if TLS 1.2 or higher is not in use
SSLDISABLELEGACYTLS
•
Defaults to NO (SSL session processing works as in prior releases, client and server negotiate TLS level)
•
YES (SSL session setup is terminated if TLS 1.2 or higher is not used)
•
Overrides the SSLTLS12=NO option
•
Enforces the rejection of SSL connection attempts that use levels earlier than TLS 1.2
•
No compliance with certificates for FCM on VMware
•
Compliance for the CIMOM device adapter with FCM on Unix/Linux
•
Unencrypted TCP protocols are still allowed
Meet National Standards
TSM Operation Center - Conformance to NIST SP800-131a
•
Secure browser to OC connection
•
During Install of OC 7.1.1 option for which type of secure connection (or none at
all) that the browser will use to connect to OC
• Off – The connection will not be secure.
• Transition – The connection will use TLS 1.0
• Strict – The connection will use TLS 1.2

TSM 7.1.1 Compress Database Backups
Description: Selectively choose which TSM database backups are compressed
Benefits:
–
–
–
–
TSM deduplication increases size of the TSM database
The space requirements have also increased when backing up the TSM database
DB backup to local media: compression doesn't add much, compression overhead can be too much
DB backup to remote media: reduced amount of data sent compensates for compression’s overhead
Server Support:
– What can be configured
• Can specify a "compress" parameter on the BACKUP DB and SET DBRECOVERY commands
• SET DBRECOVERY sets the compress defaults for the BACKUP DB command
– Impact of configuration decisions
• Processor usage and duration increased
• Increases varied based on database size, and hardware configuration
• Database backup compression decreases the size of the backed up database files
Backup file sizes: For a brand new database “sample” (backed up and compressed shortly after DSMS
TSM 7.1.1 Compress Archive Logs
Description:
• Compress DB2 archive logs
• DB2 10 introduced the ability to compress log files as they are archived
• In TSM 7.1.1
• Default to compress archive log is set to “NO”
• Known DB2 active log problem that occurs when the DB2 archive log compression flag is set to YES
• Only seen the DB2 active log problem on our large appliance CET test systems when they are under
sustained high volume usage and heavy workloads
Benefits:
• Consume less space and reduce the time required to back up the archive logs
• Potentially reduces the frequency of back ups that are initiated just to clear the archive logs
Server Support:
• Default ARCHLOGCOMPress value is No (do not compress archive logs)
• ARCHLOGCOMPress option set in the dsmserv.opt file and by the SETOPT command
• dsmserv.opt: server must be started or restarted for the option to take effect
• SETOPT command: can be used when the server is up and running
• Updates the server option immediately and appends the option and value to the dsmserv.opt file
• Current setting of the server option displayed with:
• Q LOG F=D
• Q OPT
• Q OPT ARCHLOGCOMPress
