Sun Cluster 2.2 System Administration Guide

Adding Sun StorEdge A3x00 or Sun StorEdge A1000 Enclosures

This section describes procedures used to add a Sun StorEdge A3x00 or a Sun StorEdge A1000 expansion unit. These procedures can be done with the Sun Cluster up and running.

Note -

To upgrade the firmware in expansion units, refer to the hardware service manual for your system.

How to Add a Disk Enclosure

  1. Switch over all logical hosts to one of the Sun Cluster nodes in the cluster that will be receiving the new disk enclosure. 


    phys-hahost1# haswitch phys-hahost2 hahost1 hahost2

  2. Stop Sun Cluster on the node that no longer masters any logical hosts. 


    phys-hahost1# scadmin stopnode

  3. Add the disk interface card (UDWIS) to the Sun Cluster node.

    Use the instructions that come with the UDWIS interface card.

  4. Cable the new UDWIS card to the disk enclosure.

  5. Perform a reconfiguration reboot on the node with the new UDWIS card. 


    phys-hahost1# boot -r

  6. Start Sun Cluster on the node. 


    phys-hahost1# scadmin startnode

  7. Switch over the logical hosts to another node in the cluster.


    phys-hahost1# haswitch phys-hahost1 hahost1 hahost2

  8. Perform Step 2 through Step 6 on the node that no longer masters the logical hosts.

  9. Configure the disk subsystems into the cluster.

    Use the expansion unit and VxVM documentation to set up the disk configuration.

  10. Run the haswitch(1M) command on both nodes to incorporate the new configuration into Sun Cluster.


    # haswitch -r
