If the disk status is one of the following statuses, take action 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.
You changed the I/O cable connection and booted the system.
You swapped the disk and booted the system.
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 "D.8 sdxswap - Swap disk" and "5.3.4 Disk Swap."
c) If the possible cause is (Cause c), follow the procedures and swap the disks.
However, when the cause is (Cause c) in one of the following situations, follow the procedure as described below [Resolution of Cause c].
A single disk is in DISABLE status and an INVALID single volume exists on the single disk.
A disk in DISABLE status is connected to the group and the group includes an INVALID volume.
[Resolution of Cause c]
When the disk is one of the following, contact field engineers because the class which the disk of DISABLE state belongs to must be forcibly removed.
Internal disk of SPARC M12/M10.
Internal disk of SPARC T4-4/T4-2/T4-1/T3-4/T3-2/T3-1.
Additional file unit of disk connected to the 6Gbps SAS card.
Disk connected to 12Gbps SAS card.
When the disk is a single disk
Delete the single volume in INVALID state on a single disk, and then swap the disk.
When the disk is connected to the highest level group
Delete the volume in INVALID state in the highest level group, and then swap the disk.
When the disk is connected to a lower level group
When swapping the disk, delete the INVALID volume first, and then disconnect the lower level group from the higher level group.
(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 "F.1.3 Volume Status Abnormality" or "F.1.1 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.
