PRIMECLUSTER Global Disk Services Configuration and Administration Guide 4.1 (Solaris(TM) Operating System)

4.2.3 Operation

Swap Physical Disk

Places the physical disk off-line when swapping physical disks.

For details, see "Disk Swap."

 

Restore Physical Disk

Places the swapped physical disk on-line for restoration, after swapping the physical disks.

For details, see "Disk Swap."

 

Detach Slice

Detaches one of the slices from Mirror volume to prepare for backup.

The detached slice will become accessible as a separate logical device.

For details, see "Backup (by Slice Detachment)."

 

Attach Slice

Slice detached by [Detach Slice] is attached to Mirror volume again.

For details, see "Backup (by Slice Detachment)."

 

Stop/Activate Slice

Stop Slice

In order to protect data of the slice which has been detached to prepare for backup, a slice with "temp" status will temporarily become inaccessible.

Activate Slice

The detached slice which is now inaccessible ("temp-stop" status) as a result of [Stop Slice] operation or switching of nodes will be reactivated and become accessible.

For details, see "Backup (by Slice Detachment)."

 

Start Copying

A slice with "invalid" or "copy-stop" status as a result of [Cancel Copying] operation will be attached to a mirror volume, and synchronization copying will be performed.

For details, see "Copying Operation."

 

Cancel Copying

Execution of copying will be stopped to avoid effects caused by accessing the disk in the process of synchronization copying.

For details, see "Copying Operation."

 

Start Volume

Starts the stopped volume.

 

Stop Volume

Stops the volume.

 

Proxy Operation

Operates proxy objects. This menu is available only if GDS Snapshot is installed.

 

Join

Relates proxy objects to master objects and synchronizes them as preparation for snapshot creation by synchronization, or online disk migration.

For details, see "Join."

Part

Parts joined proxies from masters temporarily to make them accessible as logical devices that are different from the masters for snapshot creation by synchronization. The parted proxies can be used as snapshots (replicas) of the masters at the moment.

For details, see "Backup (by Synchronization)."

Rejoin

Joins parted proxies to masters again and synchronizes them as preparation for snapshot re-creation by synchronization.

For details, see "Backup (by Synchronization)."

Relate

Relates proxy objects to master objects and parts them as preparation for snapshot creation by OPC.

For details, see "Relate."

Update

Copies (overwrites) data from masters to parted proxies for snapshot creation by OPC. The updated proxies can be used as snapshots (replicas) of the masters at the moment.

For details, see "Backup (by OPC)."

Restore

Copies (overwrites) data from parted proxies to masters for restoration of damaged master data. The masters are recovered by the proxy data at the moment.

For details, see "Restore."

Swap

Swaps slices of synchronized masters and proxies for online disk migration.

For details, see "Disk Migration."

Break

Breaks the relationships between masters and proxies and makes them unrelated again.

For details, see "Breaking a Proxy."

 

Change Attributes

Changes the attributes of the selected object.

For details, see "Changes."

 

Update Physical Disk Information

You can update the disk information without rebooting the system. This feature is useful in the situations given below.

• When physical disk size is not displayed properly.

• When you turn on the disk array or the disk unit after booting the system.

• When the disk has become inaccessible while operating the system.

• When the configuration of devices such as mphd or mplb has been changed.
