When swapping the following disks, follow the steps described in this section.
Internal disk of SPARC M12/M10
Internal disk of SPARC T4-4/T4-2/T4-1/T3-4/T3-2/T3-1
The disk of Expansion File Unit connected to a 6Gbps SAS card
The disk connected to a 12Gbps SAS card
In this section, these disks are called SAS disks.
If an SAS disk is swapped, the device number of the new disk may change. For this reason, an SAS disk cannot be swapped by [Swap Physical Disk] or [Restore Physical Disk] of the GDS Management View, or by the procedure to swap the physical disk by using the sdxswap command. For swapping an SAS disk, remove it from the class once, and then swap the disk device. After that, register the new disk to the class again.
The following example shows the procedures for swapping the SAS disk connected to a mirror group. In this example, the disk is mirrored and you do not need to remove volumes from the disk prior to swapping. If the disk to be swapped is not a mirrored disk, such as a single disk and a disk whose highest level group is not a mirror group, volumes must be removed from the disk prior to swapping.
In this case, first back up volume data if necessary, and then remove the volume. Next, remove the disk from the class, and after registering the new disk to the class, re-create volume and restore the data.
Identify a raw device name (devname) of the disk to be swapped by referring to the GDS I/O error messages output in the /var/adm/messages file.
To search the GDS I/O error messages, use the string "sfdsk" as a key. In the following example, the raw device name is "disk@g5000c5001d4809ff."
WARNING: sfdsk: write error on slice:

Check the device name of the disk to be swapped.
Specify the raw device name identified in step 1 as an argument of the grep command.
In the following example, the device name of the disk to be swapped is "c0t5000C5001D4809FFd0."
# ls -l /dev/rdsk | grep disk@g5000c5001d4809ff

Check the disk name, class name, and group name of the disk to be swapped.
Execute the sdxinfo -D command and find the line where the device name confirmed in step 2 is shown in the DEVNAM field.
In the following example, the disk name, class name, and the group name for the device name "c0t5000C5001D4809FFd0" are "rootDisk0002," "RootClass," and "rootGroup" respectively.

Disconnect the disk to be swapped from the group.
Specify the class name, the group name, and the disk name confirmed in step 3 for the -c, -g, and -d options of the sdxdisk -D command.
# sdxdisk -D -c RootClass -g rootGroup -d rootDisk0002 |
Note
If a spare disk is connected
When you try to disconnect the disk to be swapped while the spare disk is connected, the following error will be displayed.
SDX:sdxdisk: ERROR: spare disk connected for disk_name |
In this case, you should disconnect the spare disk first.
The following example shows the procedure to disconnect the spare disk (disk0001) before disconnecting the disk to be swapped (rootDisk0002).
# sdxinfo -D

Check if the disk to be swapped is disconnected from the group.
Execute the sdxinfo -D command and check if an asterisk (*) is displayed in the GROUP field of the disconnected disk (rootDisk0002).

Remove the disk to be swapped from the class.
Specify the class name and the disk name confirmed in step 3 for the -c and -d options of the sdxdisk -R command.
# sdxdisk -R -c RootClass -d rootDisk0002 |
Check if the disk to be swapped has been removed from the class.
Execute the sdxinfo -D command to make sure the information of the deleted disk (rootDisk0002) is not displayed.
# sdxinfo -D

Identify the identifier specific to the hardware to which the disk to be swapped is connected.
To find the identifier specific to the hardware, check the "Ap_Id" field of the information in which the device name of the disk to be swapped is displayed.
In the following example, the identifier specific to the hardware of the physical disk "c0t5000C5001D4809FFd0" is "c5::w5000c5001d4809fd."
# cfgadm -av

Swap disks.
Ask field engineers to swap your disk unit.
Both hot swap and non-hot swap are available.
Check the device name of the new disk.
For the information of identifier specific to the hardware identified in step 8, check if "unconfigured" is displayed to the Occupant and check the information displayed in "iport@X.scsi" format to the Phys_Id.
The device of the new disk is displayed as "configured" to the Occupant and "iport@X.scsi" that is checked with the above procedure is displayed to the Phys_Id.
In the following example, the device name of the new disk is "c0t5000C5001D4806BFd0."
# cfgadm -av |
Confirm that the device special file (cCtWWNdDs{0-7}) of the new disk exists.
Append an asterisk (*) to the end of the device name confirmed in step 10 and specify it as an argument of the ls command.
In the following example, you can see that the device special files from "c0t5000C5001D4806BFd0s0" to "c0t5000C5001D4806BFd0s7" exist.

If the relevant system is a cluster system, register the new disk resources with PRIMECLUSTER according to the following steps. If not, skip to step 13.
Identify the node ID of the cluster managed by PRIMECLUSTER.
In the following example, the node ID is "0."
# /etc/opt/FJSVcluster/bin/clgetnode
RID 3
KEY TRC89
RNAME TRC89
NODEID 0 |
Confirm the PRIMECLUSTER resource ID of the device (resource ID before swapping disks).
Specify the device name confirmed in step 2 above by the -k option and the node ID confirmed in step 12-1 by the -s option of the clgetrid command.
In the following example, the resource ID is "25."
# /etc/opt/FJSVcluster/sys/clgetrid -c DISK -k c0t5000C5001D4809FFd0 -s 0
25 |
Delete the disk resource of the original disk.
In the following example, delete the resource whose resource ID is 25.
# /etc/opt/FJSVcluster/bin/cldeldevice -r 25 |
Confirm that the resource of the original disk has been deleted.
Confirm that the deleted resource is not displayed.
# /etc/opt/FJSVcluster/sys/clgetrid -c DISK -k c0t5000C5001D4809FFd0 -s 0 |
Register the new disk with PRIMECLUSTER.
# /etc/opt/FJSVcluster/sys/clautoconfig -r |
Confirm that the device name of the new disk is registered.
If the device name "c0t5000C5001D4806BFd0" is displayed, the new disk has successfully been registered with PRIMECLUSTER.
