Swap Physical Disk
Places the physical disk off-line for swapping physical disks.
For details, see "7.3.1.2 Operation Procedure."
Restore Physical Disk
Places the swapped physical disk on-line for restoration after swapping physical disks.
For details, see "7.3.1.2 Operation Procedure."
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 "7.2.1 Using GDS Management View."
Attach Slice
Slice detached by [Detach Slice] is attached to Mirror volume again.
For details, see "7.2.1 Using GDS Management View."
Stop/Activate 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.
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 "7.7.1.2 Operation Procedure."
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 "7.2.1 Using GDS Management View."
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 "7.2.1 Using GDS Management View."
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.
Relates proxy objects to master objects and synchronizes them as preparation for snapshot creation by synchronization, or online disk migration.
For details, see "6.11.1.1 Join."
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 "Part."
Joins parted proxies to masters again and synchronizes them as preparation for snapshot re-creation by synchronization.
For details, see "Part."
Relates proxy objects to master objects and parts them as preparation for snapshot creation by OPC.
For details, see "6.11.1.2 Relate."
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 "7.9.1.2 Operation Procedure."
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 "7.10.1.2 Operation Procedure."
Swaps slices of synchronized masters and proxies for online disk migration.
For details, see "8.7.1.1.2 Operation Procedure."
Breaks the relationships between masters and proxies and makes them unrelated again.
For details, see "9.1 Breaking Proxy."
Change Attributes
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 resource registration was performed.
Note
When [Update Physical Disk Information] is executed, among the by-id files (symbolic link files created under the /dev/disk/by-id directory) managed by the udev function of Linux, the by-id files of disks which are not registered in classes may not exist temporarily because OS creates the by-id files again triggered by the GDS processes for obtaining the device information.
When access to the by-id files of disks which are not registered in classes fails, retry access.
Alternatively, when [Update Physical Disk Information] is executed, do not access to the by-id files of disks which are not registered in classes.
Check Status
Displays a description of the state of an object and the help to restore the object if it is faulty.
