F.1.2 Disk Status Abnormality

If the disk status is one of the following statuses, take action as indicated for the relevant situation.

• Disk is in DISABLE status.

• Disk is in SWAP status.

• Disk is in I/O error status.

(1) Disk is in DISABLE status.

 

[Explanation]

Disk ID information is checked when booting the system. If the ID information is regarded invalid at the time, the disk will become DISABLE.

There are three reasons that may cause this DISABLE status.

(Cause a)

You changed the I/O cable connection and booted the system.

(Cause b)

You swapped the disk and booted the system.

(Cause c)

Disk failure occurred.

Resolutions are described for each of the above causes.

 

[Resolution]

a) If the possible cause is (Cause a), shut down the system, connect the I/O cables correctly and boot again.

b) If the possible cause is (Cause b), shut down the system, return the original disk and boot again. If swapping the disks is necessary, follow the procedures and swap the disks. For procedures on disk swapping, see "sdxswap - Swap disk" and "Disk Swap."

c) If the possible cause is (Cause c), follow the procedures and swap the disks.

(2) Disk is in SWAP status.

 

[Explanation]

If the sdxswap -O command is executed, or [Swap Physical Disk] is performed from Operation Management View, the disk will be in SWAP status.

[Resolution]

Complete the disk swap and restore the disk by either executing the sdxswap -I command, or by performing [Restore Physical Disk] from Operation Management View.

---

 

(3) Disk is in I/O error status.

[Explanation]

If an I/O error occurs, 1 (one) is given as a value in the E field displayed with the sdxinfo -e long command and the disk icon in GDS Management View turns red. Here, the disk is in ENABLE (enabled) status.

[Resolution]

Check the statuses of volumes and slices relative to the disk with an I/O error, and perform restoration, referring to "Volume Status Abnormality" or "Slice Status Abnormality" The I/O error status is removed, during the restoration by:

• Executing [Swap Physical Disk] in GDS Management View for the relevant disk

• Executing the sdxswap -O command for the relevant disk

• Normally ending synchronization copying of volumes relative to the relevant disk

If none of the operations above are performed during the recovery and the I/O error remains unremoved, after restoring hardware and such, use the sdxfix -D command to remove the I/O error status.
