How to Add a StorEdge A5x00 Disk Drive

Use this procedure to add a disk drive to an existing cluster. Perform the steps in this procedure in conjunction with the procedures in Sun Cluster 3.0 System Administration Guide and your server hardware manual.

For conceptual information on quorum, quorum devices, global devices, and device IDs, see Sun Cluster 3.0 Concepts.

  1. On one node connected to the disk array, use the luxadm(1M) command to insert the new disk.

    Physically install the new disk drive, and press Return when prompted. Using the luxadm insert command, you can insert multiple disk drives at the same time.


    # luxadm insert enclosure,slot
    

  2. On all other nodes attached to the disk array, run the devfsadm(1M) command to probe all devices and to write the new disk drive to the /dev/rdsk directory.

    Depending on the number of devices connected to the node, the devfsadm command can take at least five minutes to complete.


    # devfsadm
    
  3. Ensure that entries for the disk drive have been added to the /dev/rdsk directory.


    # ls -l /dev/rdsk
    

  4. If needed, partition the disk drive.

    You can use either the format(1M) command or copy the partitioning from another disk drive in the disk array.

  5. From any node in the cluster, update the global device namespace.

    If a volume management daemon such as vold is running on your node, and you have a CD-ROM drive connected to the node, a device busy error might be returned even if no disk is in the drive. This error is an expected behavior.


    # scgdevs
    
  6. Verify that a device ID (DID) has been assigned to the disk drive.


    # scdidadm -l 
    

    Note -

    The DID assigned to the new disk drive might not be in sequential order in the disk array.


  7. Perform the usual volume management administration actions on the new disk drive.

    For more information, see your Solstice DiskSuite or VERITAS Volume Manager documentation.

  8. If you want this new disk drive to be a quorum device, add the quorum device.

    Refer to Sun Cluster 3.0 System Administration Guide for the procedure on adding a quorum device.
