B.3.2 cldelrsc(8)-Delete resource

SYNOPSIS

/etc/opt/FJSVcluster/bin/cldelrsc -r rid

DESCRIPTION

The "/etc/opt/FJSVcluster/bin/cldelrsc -r rid" command deletes resources from the resource database.
Resources of the following resource classes can be deleted.

Resource class name	Meaning
DISK	Resource of the shared disk unit
SHD_DISK	Shared resource of the shared disk unit
Ethernet	Resource of the network device

Use the clgettree(1) command to check the resources to be deleted.

Among shared disk unit resources, if resources in the DISK class are deleted and shared resources in the SHD_DISK class remain, it is also necessary to delete the shared resources.

Execute this command on any single node in the cluster system using system administrator access privileges.

OPTIONS

-r rid: Specify rid for the resource ID of the resource to be deleted. Check the resource ID executing the clgettree(1) command.

EXIT STATUS

0:: Normal termination.

Other than 0:: Abnormal termination.

NOTES

If a shared disk of which resources are to be deleted is registered with a GDS class, delete the shared disk from the GDS class, and then delete the resources.

EXAMPLES

The following example shows the procedure for deleting resources of a shared disk unit "/dev/sdc" shared between node1 and node2.

Perform the following procedure on any node.

Before deleting the resource, change the device name set in the resource to the current device name. Execute the following command.
For filepath, specify an empty file with an absolute path.
# /etc/opt/FJSVcluster/bin/clautoconfig -f filepath
Note
If SDX_UDEV_USE=off is described in the GDS configuration file /etc/opt/FJSVsdx/sdx.cf, you must not execute the above command.

Check the resource IDs of /dev/sdc resources using the clgettree(1) command. In the following example, the resource ID of shared disks is 17, the /dev/sdc resource ID on node1 is 18, and the /dev/sdc resource ID on node2 is 19.

# /etc/opt/FJSVcluster/bin/clgettree
  Cluster 1 cluster
    Domain 2 PRIME
        Shared 7 SHD_PRIME
                    SHD_DISK 14 SHD_Disk14 UNKNOWN
                                DISK 15 sdb UNKNOWN node1
                                DISK 16 sdb UNKNOWN node2
                    SHD_DISK 17 SHD_Disk17 UNKNOWN
                                DISK 18 sdc UNKNOWN node1
                                DISK 19 sdc UNKNOWN node2
        Node 3 node1 ON
                    DISK 15 sdb UNKNOWN
                    DISK 18 sdc UNKNOWN
        Node 5 node2 ON
                    DISK 16 sdb UNKNOWN
                    DISK 19 sdc UNKNOWN

Delete the resources of the shared disk unit "/dev/sdc" using the cldelrsc(8) command.

# /etc/opt/FJSVcluster/bin/cldelrsc -r 17
# /etc/opt/FJSVcluster/bin/cldelrsc -r 18
# /etc/opt/FJSVcluster/bin/cldelrsc -r 19
