How to Add a Disk Drive to a StorEdge A5x00 Array in a Running Cluster

Use this procedure to add a disk drive to a running cluster. Perform the steps in this procedure in conjunction with the procedures in the Sun Cluster 3.0 12/01 System Administration Guide and your server hardware manual.

For conceptual information on quorums, quorum devices, global devices, and device IDs, see the Sun Cluster 3.0 12/01 Concepts document.

  1. On one node that is connected to the StorEdge A5x00 array, use the luxadm insert_device (1M) command to install the new disk.

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


    # luxadm insert_device enclosure,slot

  2. On all other nodes that are attached to the StorEdge A5x00 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 require 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 necessary, partition the disk drive.

    You can use either the format(1M) command or copy the partitioning from another disk drive in the StorEdge A5x00 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 that was assigned to the new disk drive might not be in sequential order in the StorEdge A5x00 array.

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

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

To configure a disk drive as a quorum device, see the Sun Cluster 3.0 12/01 System Administration Guide for the procedure on adding a quorum device.
