Managing Serviceguard Eighteenth Edition, September 2010

These commands create a configuration file which you can apply to the cluster
configuration when you are ready to do so; see “Distributing the Binary Configuration
File ” (page 259). See also “Specifying a Lock LUN” (page 247).
CAUTION: Once you have specified the lock LUN in the cluster configuration file,
running cmapplyconf (1m) or cmdeploycl (1m) will destroy any data on the
LUN.
Excluding Devices from Probing
When you run cmquerycl (1m) or cmdeploycl (1m) to configure the cluster,
Serviceguard probes disk devices (devices with paths that begin with /dev/dsk/ and
/dev/disk) to see if they are configured under the LVM, LVM2, or VxVM volume
manager. By design, devices such as CD and DVD drives are omitted, but occasionally
such a device may use a description string that Serviceguard does not recognize. The
description string appears in the Description field of the output of ioscan -funC
disk, and you can see what types of device Serviceguard will exclude from probing
by looking at the TYPE field of the file /etc/cmcluster/cmignoretypes.conf.
NOTE: You should not edit cmignoretypes.conf
If Serviceguard does not recognize a device, you will see an error such as the following
when you run cmquerycl:
Error reading device /dev/dsk/c0t0d0 0x8
Note: Disks were discovered which are not in use by either LVM or VxVM.
Use pvcreate(1M) to initialize a disk for LVM or,
use vxdiskadm(1M) to initialize a disk for VxVM.
In this example, Serviceguard did not recognize the type of the device identified by
/dev/dsk/c0t0d0. You can fix the problem by adding a line for this device to the
file /etc/cmcluster/cmnotdisk.conf; in this example, you would add:
DEVICE_FILE="/dev/dsk/c0t0d0"
Now when you run cmquerycl, if you still have disks that are not being managed by
LVM, LVM2 or VxVM, you will see output such as the following:
cmquerycl -C test.conf -n pig
Note: Disks were discovered which are not in use by either LVM or VxVM.
Use pvcreate(1M) to initialize a disk for LVM or,
use vxdiskadm(1M) to initialize a disk for VxVM.
