Example--Adding Another Host to a Disk Set

# metaset -s blue -a -h idiom
# metaset -s blue
Set name = blue, Set number = 1
 
Host                Owner
  lexicon                Yes
  idiom
 
Drive               Dbase
  c1t6d0             Yes 
  c2t6d0             Yes 

This example shows the addition of host idiom to the disk set blue.

How to Create Solaris Volume Manager Components in a Disk Set

After you create a disk set, you can create volumes and hot spare pools using the drives you added to the disk set. You can use either the Enhanced Storage tool within the Solaris Management Console or the command line utilities.

1. To create volumes or other Solaris Volume Manager devices within a disk set, use one of the following methods:

   • From the Enhanced Storage tool within the Solaris Management Console, open the Volumes, State Database Replicas, or Hot Spare Pools node. Choose Action->Create, then follow the instructions in the wizard. For more information, see the online help.

   • Use the command line utilities with the same basic syntax you would without a disk set, but add -s diskset-name immediately after the command for every command.

Example--Creating Solaris Volume Manager Volumes in a Disk Set

# metainit -s blue d11 1 1 c1t6d0s0
blue/d11: Concat/Stripe is setup
# metainit -s blue d12 1 1 c2t6d0s0
blue/d12: Concat/Stripe is setup
# metainit -s blue d10 -m d11           
blue/d10: Mirror is setup
# metattach -s blue d10 d12
blue/d10: submirror blue/d12 is attached

# metastat -s blue
blue/d10: Mirror
    Submirror 0: blue/d11
      State: Okay         
    Submirror 1: blue/d12
      State: Resyncing    
    Resync in progress: 0 % done
    Pass: 1
    Read option: roundrobin (default)
    Write option: parallel (default)
    Size: 17674902 blocks

blue/d11: Submirror of blue/d10
    State: Okay         
    Size: 17674902 blocks
    Stripe 0:
        Device              Start Block  Dbase State        Reloc  Hot Spare
        c1t6d0s0                   0     No    Okay                


blue/d12: Submirror of blue/d10
    State: Resyncing    
    Size: 17674902 blocks
    Stripe 0:
        Device              Start Block  Dbase State        Reloc  Hot Spare
        c2t6d0s0                   0     No    Okay                

This example shows the creation of a mirror, d10, in disk set blue, that consists of submirrors (RAID 0 devices) d11 and d12.

Maintaining Disk Sets

How to Check the Status of a Disk Set

1. Use one of the following methods to check the status of a disk set.

   • From the Enhanced Storage tool within the Solaris Management Console, open the Disk Sets node. Right-click the Disk Set you want to monitor, then choose Properties from the menu. For more information, see the online help.

   • Use the metaset command to view disk set status.

     See metaset(1M) for more information.

     ---

     Note - Disk set ownership is only shown on the owning host.

     ---

Example--Checking the Status of a Specified Disk Set

red# metaset -s blue


Set name = blue, Set number = 1

Host                Owner
  idiom             Yes 

Drive               Dbase
  c1t6d0             Yes 
  c2t6d0             Yes 

The metaset command with the -s option followed by the name of the blue disk set displays status information for that disk set. By issuing the metaset command from the owning host, idiom, it is determined that idiom is in fact the disk set owner. The metaset command also displays the drives in the disk set.

The metaset command by itself displays the status of all disk sets.

How to Remove Disks from a Disk Set

To delete a disk set, you must first delete all drives from the disk set.

• From the Enhanced Storage tool within the Solaris Management Console, open the Disk Sets node. Right-click the Disk Set you want to release, then choose Properties from the menu. Click the Disks tab and follow the instructions in the online help.

• Use the following form of the metaset command:

  metaset -s diskset-name-d drivename

  
  

  -s diskset-name	Specifies the name of a disk set on which the metaset command will work.
  drive-name	Specifies the drives to delete from the disk set. Drive names are in the form cxtxdx; no "sx" slice identifiers are at the end of the name.

  See the metaset(1M) man page for more information.

1. Verify that the disk has been deleted from the disk set by using the metaset -s diskset-name command.

   # metaset -s blue
