D.1.2 Disk Status Abnormality

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

(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.

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 disk swap is necessary, follow the procedures and swap the disks.
For the procedures for swapping disks, see "B.1.8 sdxswap - Swap Disk" and "7.3.1.2 Operation Procedure."

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

The following action is necessary.

(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.

Note

When an I/O error has occurred in the root class, the E field of the disk information shown by the sdxinfo -e long command will not display "1" which indicates the I/O error status. Check the I/O error information using system log etc.

Resolution

Check the statuses of volumes and slices relative to the disk with an I/O error, and perform restoration, referring to "D.1.3 Volume Status Abnormality" or "D.1.1 Slice Status Abnormality" The I/O error status is removed, during the restoration by:

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.
