Tasks Associated With Multi-Owner Disk Sets


Caution – Caution –

Before configuring multi-owner disk sets, you must have the following software installed, in addition to the Solaris OS:

Solaris Volume Manager for Sun Cluster generally uses the same set of Solaris Volume Manager commands to perform tasks associated with disk sets. Some command options unique to multi-owner disk sets have been added to the metaset command. For example, the task to create a multi-owner disk set requires the -M to the metaset command. The following output shows you how to create a multi-owner disk set using the metaset -s diskset-name -a -M -h hostname command.


# metaset -s red -a -M -h nodeone
# metaset
Multi-owner Set name = red, Set number = 1, Master = 

Host                Owner          Member
  nodeone                          Yes 

In addition, some of the metaset command options, such as the commands to take and release disk sets, are not used with multi-owner disk sets. For more information, see the metaset(1M) man page.

Another example of how tasks differ in a Sun Cluster environment occurs when working with disks. Sun Cluster assigns each disk a unique device ID (DID) number. Rather than using the cntndn format to identify a disk, use the Sun Cluster DID path name, /dev/did/dsk/dN. The variable N is the device number assigned by Sun Cluster.

The following output shows you how to add a disk to a multi-owner disk set using the metaset -s diskset-name -a disk-name command and the Sun Cluster DID path name to identify the disk.


nodeone# metaset -s red
Multi-owner Set name = red
Multi-owner Set name = red, Set number = 1, Master = 

Host                Owner          Member
  nodeone                           Yes 
  nodetwo                           Yes 
nodeone# metaset -s red -a /dev/did/dsk/d13
nodeone# metaset -s red
Multi-owner Set name = red, Set number = 1, Master = nodeone

Host                Owner          Member
  nodeone            multi-owner   Yes

Drive Dbase

d13   Yes
