Repairing or rebuilding the /cms file system45
Repairing or rebuilding the /cms file system3
This section contains procedures for reinitializing the /cms file system. 
You may need to perform this procedure in case of disk corruption or 
some other catastrophic system problem. The point of the procedure is to 
repair 
/cms or, failing that, to rebuild it and restore the latest available 
CMS data. Try to repair the file system first: if you can repair it, you will 
save considerable time and trouble.
Repairing /cms3This procedure attempts to repair /cms.
1. Turn off CMS.
a. Enter a cmsadm
 or cmssvc
 command.
b. Select the run_cms
 option.
c. Select the Turn off CMS
 option.
2. Unmount 
/cms:
The system prompt should return without messages, as shown.
3. Do this step only if the umount
 command returned the 
response /cms: device busy
.
a. Load the 
/etc/vfstab file into your editor.
b. Find the /cms
 and /cms/swap
 lines. Comment out both lines. 
(To comment out a line, insert a pound sign at the beginning.)
c. Save the file and exit the editor.
d. Reboot by entering the following command:
4. Attempt to repair /cms:# umount /cms
#
# /usr/sbin/shutdown -i6 -g0 -y
# fsck -y /dev/md/rdsk/d21
** /dev/md/dsk/d21
** Last mounted on /cms
** Phase 1 - Check Blocks and Sizes
** Phase 2 - Check Pathnames
** Phase 3 - Check Connectivity
** Phase 4 - Check Reference Counts
** Phase 5 Check Cyl groups

Repairing or rebuilding the /cms file system46
The system prompt should return without error, as shown above. (Of 
course, file and block counts in the last line will vary.) In that case, 
continue with the next step. 
If you get an error message, however, repeat the fsck
 command. If 
the command still returns errors after 10 repetitions, stop this 
procedure and skip ahead to “Rebuilding /cms,” below.
Continue with step 6 only if you entered the fsck command and 
it returned the system prompt without error messages.
5. This step remounts 
/cms and reallocates the swap file. How that is 
done depends upon whether you altered the 
vfstab file earlier in this 
procedure.
If you altered the 
vfstab file earlier (step 4), do the following:
a. Load the 
/etc/vfstab file into your editor.
b. Find the #/cms
 line. Uncomment the line. (To uncomment a 
line, delete the initial pound sign.)
c. Save the file and exit the editor.
d. Reboot by entering the following command:
If you did NOT alter the 
vfstab file, do the following:
a. Remount 
/cms:
6. Turn on CMS:
a. Enter a cmsadm
 or cmssvc
 command.
b. Select the run_cms
 option.
c. Select the Turn on CMS
 option.
The file system has now been repaired and should be operating normally.
If this procedure completed successfully, do NOT do the “Rebuild 
/cms” procedure.
Rebuilding /cms3Do this procedure only if you have tried the fsck command at least 
ten times and it is still returning errors.
If you are running a 
Sun Enterprise 3500 platform, do not begin this 
procedure until you have checked the 
/kernel/drv/st.conf file to make sure 
the 3500’s 8mm tape drive is properly defined. See “Restoring from a 
CMSADM Backup” on page 43 for details.
To complete this procedure, you need the latest CMSADM backup. Also, 
/cms should still be unmounted at this point. If anything has been done to 
alter that, repeat steps 2 through 4 of the “Repairing /cms” procedure.# /usr/sbin/shutdown -i6 -g0 -y
# mount /cms

1. Add the 
Solstice DiskSuite directories to your path:
2. Detach the d20 submirror:
3. Clear the d20 submirror:
4. Clear the cms mirror:
5. Clear the d19 submirror:
6. Reinitialize the d19 submirror:
7. Reinitialize the d20 submirror:
8. Reinitialize the cms mirror:# export PATH=$PATH:/usr/opt/SUNWmd/sbin:/olds
#
# metadetach d21 d20
d21: submirror d20 is detached
#
# metaclear d20
d20: Concat/Stripe is cleared
#
# metaclear d21

9. Prepare the cms mirror for a new file system (this will take 15 to 30 
minutes to complete):
10. This step remounts 
/cms. How that is done depends upon whether 
you had to alter the 
vfstab file when you attempted to repair the file 
system.
If you altered the 
vfstab file during the repair procedure, do the 
following:
a. Load the 
/etc/vfstab file into your editor.
b. Find the #/cms
 line. Uncomment the line. (To uncomment a 
line, delete the initial pound sign.)
c. Save the file and exit the editor.
d. Reboot by entering the following command:
If you did NOT alter the 
vfstab file, do the following:
a. Remount 
/cms:
11. Verify that you are in the root directory.
12. Load the latest CMSADM backup tape into the tape drive.
13. Restore CMS data from the tape:
14. Restore the latest full maintenance backup.# newfs -m 0 /dev/md/rdsk/d21

Restoring a mirrored system from a CMSADM backup49
Restoring a mirrored system from a CMSADM backup3
This section shows you how to restore an entire mirrored system from a 
CMSADM backup. You might have to do this procedure, for example, if 
you have a disk crash that disables the operating system disk drive.
To do this procedure, you will need the “
Solaris 7 3/99” compact disc and 
the most recent CMSADM backup tape. You will also need to know your 
system’s host name, host ID, and IP address. 
Step 1: Power off 
the system
3
Power off the system by doing the following tasks:
1. Turn off the system unit.
2. Turn off the system monitor.
3. Turn off all external devices starting with the device closest to the 
system unit and working toward the farthest device.
Step 2: Install the 
new drives
3You must wear an ESD wrist strap when installing or removing hard disk 
drives to prevent electrical discharge that may harm system components.
In Sun Enterprise 3xxx systems, the internal hard disk drives install in the 
front of the system. To expose the disk drive bays, open the front access 
door. 
Each disk drive has a retainer latch/drive handle on the front of the drive. 
To install a drive, unlatch and extend the retainer and slide the drive 
carefully into the appropriate drive slot. When the drive stops, gently 
apply pressure to the face of the drive until you hear the connectors 
engage. Then lower the retainer latch and snap it in place, making certain 
the drive is secure and does not extend beyond the front of the chassis.
Do not use excessive force to seat the connector or to close the retainer 
latch.
For additional information about hard disks and disk drives, see the 
Sun 
System Reference Manual
 appropriate to your hardware platform.
