Disk errors

Types of disk errors described

The filer displays error messages when the following disk problems occur:

Error message: Nonexistent disks

If you get a message indicating that a disk does not exist, especially if you are adding a disk to a volume or a RAID group, make sure that

Error message: Disk in use

If you are adding a disk to a volume and you get a message indicating that a disk is in use, the disk you specified might already be a system disk. Make sure that

Error message: System cannot boot because disks are missing

You might get a message similar to the following:

The system cannot boot with more than one disk missing from a RAID 
group.

This message indicates that a volume might be missing some disks because either not all the disks in a volume were transferred to a new filer or disks were damaged.

Make sure that all the disks in a volume were transferred. If the problem persists, it might mean that disks were damaged. Complete the steps in the following table to resolve the problem.

Step Action
1 Display the boot menu from diskette, as described in "Booting from system boot diskette", then choose Maintenance mode boot.
2 Use the vol offline command to take the volume off-line.
3 Reboot the filer; the volume specified in Step 2 is off-line.
4 Add missing disks, if possible, then bring them on-line; otherwise, follow these steps:
  1. Replace any broken disks.
  2. Destroy the old volume.
  3. Create a new volume.
  4. Use the restore command to restore the contents of the old volume from a backup tape.
