How to Create a Sun StorEdge T3 Disk Tray Logical Volume

Use this procedure to create a Sun StorEdge T3 disk tray logical volume. This procedure assumes all cluster nodes are booted and attached to the Sun StorEdge T3 disk array that will host the Sun StorEdge T3 disk tray logical volume you want to create.

  1. Telnet to the Sun StorEdge T3 disk array that will host the Sun StorEdge T3 disk tray logical volume you want to create.

  2. Create the Sun StorEdge T3 disk tray logical volume.

    Creating a Sun StorEdge T3 disk tray logical volume involves adding, mounting, and initializing a Sun StorEdge T3 disk tray logical volume.

    For the procedure on creating and initializing a Sun StorEdge T3 disk tray logical volume, see the Sun StorEdge T3 Disk Tray Administrator's Guide. For the procedure on mounting a Sun StorEdge T3 disk tray logical volume, see the Sun StorEdge T3 Installation, Operation, and Service Manual.

  3. On all cluster nodes, update the /devices and /dev entries.

    Solaris 2.6:


    # drvconfig
# disks -C
# devlinks

    Solaris 8:


    # devfsadm -C

    After this process, a Solaris logical device name for the new Sun StorEdge T3 disk tray logical volume appears in the /dev/rdsk and /dev/dsk directories on all cluster nodes attached to the Sun StorEdge T3 disk array.

  4. If needed, partition the Sun StorEdge T3 disk tray logical volume.

  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 expected behavior.


    # scgdevs

To create a new logical host or reconfigure a running logical host to use the new Sun StorEdge T3 disk tray logical volume, see the Sun Cluster 2.2 Software Installation Guide.

How to Remove a Sun StorEdge T3 Disk Tray Logical Volume

Use this procedure to remove a Sun StorEdge T3 disk tray logical volume. This procedure also assumes all cluster nodes are booted and attached to the Sun StorEdge T3 disk array that hosts the Sun StorEdge T3 disk tray logical volume you want to remove.

Caution - Caution -

This procedure removes all data on the Sun StorEdge T3 disk tray logical volume you want to remove.

  1. If necessary, migrate all data and volumes off the Sun StorEdge T3 disk tray logical volume you want to remove. Otherwise, proceed to Step 3.

  2. Determine if the Sun StorEdge T3 disk tray logical volume you want to remove is a quorum device.


    # scstat -q

    If the disk drive you want to remove is a quorum device, put the quorum device into maintenance state before you proceed. Otherwise, proceed to Step 1.

    For the procedure on putting a quorum device into maintenance state, see the Sun Cluster 3.0 U1 System Administration Guide.

  3. Run the appropriate Solstice DiskSuite or VERITAS Volume Manager commands to remove the reference to the logical unit number (LUN) from any diskset or disk group.

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

  4. Telnet to the Sun StorEdge T3 disk array that hosts the Sun StorEdge T3 disk tray logical volume you want to remove.

  5. Remove the Sun StorEdge T3 disk tray logical volume.

    For the procedure on deleting a Sun StorEdge T3 disk tray logical volume, see the Sun StorEdge T3 Disk Tray Administrator's Guide.

  6. On all cluster nodes, update the /devices and /dev entries.

    Solaris 2.6:


    # drvconfig
# disks -C
# devlinks

    Solaris 8:


    # devfsadm -C
