14
SCO OpenServer 6 – updated Features
Major Kernel Difference [1]:
• Dynamically loadable modules:
•
•
•
•
Allows loading of drivers without a kernel relink and reboot
modadmin –s to list loaded modules
modadmin –l <mod_name> to load a module
Modules held in:
 /etc/conf/mod.d
• To make a module static:
 Add “$static” to /etc/conf/sdevice.d/<mod_name>
 Relink the kernel
• Modules can be removed from the loaded set by the
kernel to save resources (eg, RAM)
15
SCO OpenServer 6 – updated Features
Major Kernel Difference [2]:
• Kernel Relink
• Linking is deferred by default until reboot
• Kernel Autotuning
• Kernel tunables are set based on amount of memory detected at
boot
• See Autotune(4) for more details
• All UW and OSR5 Device Names provided
• OSR5 takes precedence if there is a clash
16
SCO OpenServer 6 – updated Features

• Support for following filesystems:
•
•
•
•
•
•
VXFS
HTFS (no journalling)
EAFS (boot filesystem)
AFS and S51k
dosfs supporting DOS, VFAT, FAT 12, FAT16, FAT32(New)
cdfs supporting JOILET(New), Rockridge, ISO9660 and High
Sierra
• Raw Slice/Division
• Memfs (Improved)
• NFS
• Xenix and DTFS filesystem types not supported
17
SCO OpenServer 6 – updated Features
Major Filesystem Differences [2]:
• VXFS Filesystem Supports:
• > 64k inodes
• File size up to 1Tb
•
•
•
•
Encrypted filesystems supported using marry(ADM)
Support for up to 15 divisions/slices per partition
/stand is mounted read/write
fdisk(ADM) now supports writing of Masterboot
18
SCO OpenServer 6 – updated Features
Major Filesystem Differences [3]:
• both SCSI & IDE follows the very same naming scheme
• /dev/[r]dsk/c#b#t#d#s#
• /dev/[r]dsk/c#b#t#d#p#
• where:
•
•
•
•
•
•
•
# is a hex number (0-F)
c# is the SCSI/IDE controller number of the device (starting from 0)
b# is the HBA bus number (SCSI) - always 0 for IDE devices
t# is the SCSI ID number - for IDE, 0 = master, 1 = slave
d# is the SCSI LUN - always 0 for IDE
s# is the slice number
p# is the partition number, where p0 means the whole disk
19
SCO OpenServer 6 – updated Features
Steps to create an Encrypted filesystem [1]:
• Create a regular file with appropriate permissions
• touch <regfile>
• Create a mount point with the correct permissions
• mkdir <mount_point>
• Create the block special device using marry(ADM)
• cryptfs=`marry –a –b blksz –c “passphrase” regfile`
• Note 5 of the blksz blocks (512 bytes) are used for encryption
information
20
SCO OpenServer 6 – updated Features
Steps to create an Encrypted filesystem [2]:
• Make a filesystem on the marry device using:
• mkfs -f vxfs $cryptfs blksz-5
• Mount the filesystem on the mountpoint using:
• mount $cryptfs <mount_point>
21
SCO OpenServer 6 – updated Features
Examples of accelerated networking: NFS v3 [1]
•
Version 2 clients can access only the lowest 2GB of a file (signed 32 bit
offset).
•
Version 3 clients support larger files (up to 64 bit offsets). Maximum file
size depends on the NFS server's local file systems.
•
NFS Version 2 limits the maximum size of an on-the-wire NFS read or
write operation to 8KB (8192 bytes).
•
NFS Version 3 over UDP theoretically supports up to 56KB (not to
mention you can have NFS over TCP with version 3)
22
SCO OpenServer 6 – updated Features
Examples of accelerated networking: NFS v3 [2]
• NFS Version 2 requires that a server must save all the data in a
write operation to disk before it replies to a client that the write
operation has completed.
• This can be expensive because it breaks write requests into small
chunks (8KB or less) that must each be written to disk before the
next chunk can be written.
• Disks work best when they can write large amounts of data all at
once.
23
SCO OpenServer 6 – updated Features
Examples of accelerated networking: NFS v3 [3]
• NFS Version 3 introduces the concept of "safe asynchronous
writes."
• A Version 3 client can specify that the server is allowed to reply
before it has saved the requested data to disk, permitting the
server to gather small NFS write operations into a single efficient
disk write operation.
• A Version 3 client can also specify that the data must be written to
disk before the server replies, just like Version 2 does
24
SCO OpenServer 6 – updated Features
Examples of accelerated networking: NFS v3 [4]
•
"Seeing is believing" test 1:
•
NFS writing from a client box to a shared folder on SCO OS 5.0.7 and 6.0.0 of a
100MB archive on a PIII-700Mhz, 128MB, Intel Pro 10/100 network card using a
crossed network cable
NFS
SCO OS 5.0.7
SCO OS 6.0.0
20.52 seconds (1)
23.94 seconds (2)
8.78 seconds (3)
(1) NFS writes completely Asynch'd
(2) NFS writes mostly Asynch'd (kernel hack)
(3) NFS v3 over TCP/IP (default configuration)
25
SCO OpenServer 6 – updated Features
Examples of accelerated I/O: VxFS filesystem [1]
•
VxFS uses the intent logging feature:
•
before committing an I/O request to disk, the filesystem writes it to a
“circular log” (journal)
•
if there’s a crash, on startup the system examines the log searching for
pending operations and committing them if necessary
•
result: a much faster filesystem check which has only to check the log file
instead of the whole filesystem (which gives a faster boot especially for
very large filesystem – fsck’s –ofull option still applies if needed)
26
SCO OpenServer 6 – updated Features
Examples of accelerated I/O: VxFS filesystem [2]
•
"Seeing is believing" test 2:
•
•
glimpseindex compiled under SCO OS 5.0.4 and ported "as-is" onto
OpenServer 6.0.0
mission: the reindexing of a 96MB (2700 files) and 400MB (9000 files) archive
under the same HW box (old PIII-700, 128MB of RAM, 20GB EIDE HD) with
2 partitions (SCO OS 5.0.7 HTFS and 6.0.0 VxFS)
96MB

27
SCO OpenServer 6 – updated Features
Examples of accelerated I/O: VxFS filesystem [3]
•
"Seeing is believing" test 3:
•
•
•
given the above 400MB folder, create a tar file on the local (root) filesystem
under SCO OS 5.0.7, the filesystem is HTFS
under SCO OS 6.0.0, the filesystem is the new VxFS

213 seconds
28
SCO OpenServer 6 – updated Features
Examples of enhanced I/O: large fs (LFS) [1]
• LFS enabled by default of Root filesystem is vxfs
• Check that LFS its enabled using:
• fsadm / (should report unlimited)
• To allow for the creation of large files run:
• ulimit unlimited
• Applications from OSR5 must be ported to take
advantage of LFS
• Use open64(S) instead of open(S)
• Use stat64(S) instead of stat(S) etc
29
SCO OpenServer 6 – updated Features
Examples of enhanced I/O: large fs (LFS) [2]
• Test Large Filesystem Support using:
• dd if=/dev/zero of=big bs=1024k count=2100
• ls -l big
• Utilities that are Large File Aware:
•
•
•
•
•
•
•
cat(1), du(1), pathchk(1), chgrp(1), ff(1M)
pax(1), chmod(1), find(1), pwd(1), chown(1)
fsck(1M), cksum(1), fsdb(1M), rm(1)
cmp(1), ln(1), rmdir(1), compress(1), ls(1), sum(1)
cp(1), mkdir(1), rcp(1) touch(1), cpio(1), mkfs(1M), ulimit(1)
dd(1M), mv(1), uncompress(1), df(1M) ncheck(1M), zcat(1)

30
SCO OpenServer 6 Commands & utils
Command and Utility Differences [1]:
• OpenServer 6 contains:
• Many OpenServer 5 commands and utilities
 Some are redundant (e.g. badblk(ADM) )
 Some updated OpenServer 5 commands and utilities
 e.g. cpio(C) now handles large files
 Some new commands and utilities
 e.g. sdiadd(ADM) supports a new features of OSR6
 Some SVR5 commands for compatibility with UnixWare
 These are found in /udk/bin
 Some LFS commands that are not OSR5 compatible
 These are found in /u95/bin
31
SCO OpenServer 6 Commands & utils
Command and Utility Differences [2]:
• pstat(C) has been removed, use crash(ADM)
instead
• kprf(ADM) and kprpt(ADM) replaced by
prfstat(ADM), prfsnap(ADM) and prfpr(ADM)
• The following commands are obsolete:
• eisa(ADM), pipe(ADM), pipestat(ADM) and tickadj(ADM)
• badblk(ADM) and badtrk(ADM) dkinit(ADM)
32
SCO OpenServer 6 Commands & utils
Command and Utility Differences [3]:
• Large Filesystem Aware commands will all be
based on UnixWare commands with exception of
cpio(C)
• SCO OpenServer 6 PATH recommendation:
• /bin
- traditional OSR5 user
• /u95/bin:/bin - traditional OSR5 user who wants LFS
• /udk/bin:/u95/bin:/bin - users running a UW7 app
