Rebuilding /cms

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:

# /usr/sbin/shutdown -i6 -g0 -y

If you did NOT alter the vfstab file, do the following:

a.Remount /cms:

# mount /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.

Do 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.
