Excluded Device List (/etc/opt/FJSVsdx/lib/exdevtab file) is a disk list which is to be excluded from GDS management.
In the Excluded Device List, describe disks such as a native device (sd device) which composes multipath disks (mpath and emcpower devices) that are to be excluded from GDS management.
Example of the Excluded Device List:
# cat /etc/opt/FJSVsdx/lib/exdevtab
/dev/sde
/dev/sdf
/dev/sdg
/dev/sdh |
Disks described in the Excluded Device List are protected so that they cannot be mistakenly registered with a class.
For the GDS Management View, disks are not displayed in the selection screen.
If an attempt to register a disk with a class by a command, an error message "ERROR: physical_disk_name: no such device" is output.
Note
For PRIMECLUSTER Systems
In a PRIMECLUSTER system, create Excluded Device Lists on all nodes that constitute the cluster.
Devices that cannot be managed with GDS are also nontargets of resource registration, and do not describe these devices in the shared disk definition file. For details on resource registration and the shared disk definition file, see "6.3 Shared Disk Resource Registration."
Note
Device Name Change
When device name change occurs, change the device name described in the Excluded Device List to the name after device name change occurs.
