PRIMECLUSTER GDS (referred to as "GDS")/SynfinityDISK is software whose main function is mirroring disk units.
The operation modes supported by Tape Backup of AdvancedCopy Manager are as follows.
For operation in units of slices
[Solaris]
/dev/sfdsk/(class name)/dsk/(volume name):(devnam-value-of-sdxinfo)
[Linux]
/dev/sfdsk/(class name)/dsk/(volume name):(device name)
One of the following is used for the device name that makes up of volume.
sdxinfo@DEVNAM value
Example of using the sdxinfo@DEVNAM value for the operation of a slice unit is described below:
Example:/dev/sfdsk/class1/dsk/volume1:sda
Class name:class1
Volume name:volume1
Device name:sda(sdxinfo DEVNAM value)
Device name (udev devide name) generated by the udev mechanism specified by sdxinfo DEVNAM sdxinfo DEVNAM value.
An example of using udev device name for the operation of a slice unit is described below.
Example)/dev/sfdsk/class1/dsk/volume1:/dev/disk/by-id/scsi-3600e000000cb00000000000100020000
Class name:class1
Volume name:volume1
Device name:/dev/disk/by-id/scsi-3600e000000cb00000000000100020000(udev device name specified by the sdxinfo DEVNAM value)
The udev device name is used as the priority under the environment in which udev device name exists. The udev device name can use the by-id name. If the udev device name is used but by-id is not generated, by-id should be generated. If a backup operation is performed by the tape backup option under the environment where only the by-path name is generated, the format should be changed to the conventional format (compatible device name) according to "stgxfwcmsetmode (Information capture mode setting command)" in the "ETERNUS SF AdvancedCopy Manager Operator's Manual (Linux version)". Even if in the environment where the udev device exists and the sdxinfo DEVNAM value is used, the mode should be changed to the information capture mode prior to device information capture/reflection processing in order to avoid the use of udev device name.
For details, refer to "stgxfwcmsetmode (Information capture mode setting command)" in the "ETERNUS SF AdvancedCopy Manager Operator's Manual (Linux version)".
[Windows]
disk class name/mirror volume:g?d?p?
Note
Operation mode for the logical volume units is not supported.
Solaris and Linux are the only supported operating systems.
Notes on Linux
The following are notes on using PRIMECLUSTER GDS/SafeDISK SDX object in the tape backup option.
The by-id name should be used when the udev device name is used.
If the by-id name is not generated, the settings should be changed to generate the by-id name. The operation is not possible with by-path.
Note the following if the udev device is used under the environment where the ETERNUS multipath driver is not installed.
If the disk is replaced while using by-id, the udev device name may change. Even if the udev device name is changed, the procedure for "Change of the device configuration" is required.
