4.1.5 How to Put a Quorum Device Into Maintenance State

Put a quorum device into maintenance state when taking the quorum device out of service for an extended period of time. This way, the device's quorum vote count is set to zero and does not contribute to the quorum count while the device is being serviced.

You need to use the scconf(1M) command to put a quorum device into the maintenance state. The scsetup utility does not have the ability to put a quorum device into maintenance state.

All two-node clusters require at least one configured quorum device. If this is the last quorum device on a two-node cluster, scconf will fail to put the device into maintenance state.

1. Become superuser on a node of the cluster.

2. Put the quorum device into the maintenance state.

   # scconf -c -q globaldev=device,maintstate

   -c

   Specifies the change form of the scconf command.

   -q

   Manages the quorum options.

   globaldev=device

   Specifies the DID name of the disk device to change, for example, d4.

   maintstate

   Puts the node into maintenance state.

3. Verify that the quorum device is now in maintenance state.

   The output for the device you placed in maintenance state should read zero for the Quorum Device Votes.

   # scconf -p | grep -i quorum

4.1.5.1 Example--Putting a Quorum Device Into Maintenance State

The following example shows how to put a quorum device into maintenance state and how to verify the results.

# scconf -c -q globaldev=d20,maintstate
# scconf -p | grep -i quorum
  Node quorum vote count:                          1
  Node quorum vote count:                          1
Quorum devices:                                    d20
Quorum device name:                                d20
  Quorum device votes:                             0
  Quorum device enabled:                           no
  Quorum device path:                              /dev/did/rdsk/d20s2
  Quorum device hosts (enabled):                   phys-schost-2 phys-schost-3
  Quorum device hosts (disabled): 

4.1.5.2 Where to Go From Here

When you have completed the maintenance procedure on the quorum device, and want to re-enable the quorum device, see "4.1.7 How to Bring a Node Out of Maintenance State and Reset Quorum" to reset the quorum device's vote back to the default.
