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

Where to Go From Here

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

Where to Go From Here

To create a Sun StorEdge T3 disk tray logical volume, see the "How to Create a Sun StorEdge T3 Disk Tray Logical Volume".

Maintaining a Sun StorEdge T3 Disk Array

This section provides the procedures for maintaining a Sun StorEdge T3 disk array. The following table lists these procedures. This section does not include a procedure for adding a disk drive because a Sun StorEdge T3 disk array only operates when fully configured. Moreover, this section does not include a procedure for removing a disk drive because you must replace, within 30 minutes, any FRUs you remove.

Caution - Caution -

If you remove any field replaceable unit (FRU) for an extended period of time, thermal complications might result. To prevent this complication, the Sun StorEdge T3 disk array is designed so an orderly shutdown occurs when you remove a component for longer than 30 minutes. A replacement part must be immediately available before starting a FRU replacement procedure. You must replace a FRU within 30 minutes or the Sun StorEdge T3 disk array, and all attached Sun StorEdge T3 disk arrays, will shut down and power off.

How to Upgrade Sun StorEdge T3 Disk Array Firmware

Use this procedure to upgrade Sun StorEdge T3 disk array firmware in a running cluster. Sun StorEdge T3 disk array firmware includes controller firmware, unit interconnect card (UIC) firmware, and disk drive firmware.

Caution - Caution -

Perform this procedure on one Sun StorEdge T3 disk array at a time. This procedure requires that you reset the Sun StorEdge T3 disk array you want to upgrade. If you reset more than one Sun StorEdge T3 disk array, your cluster will lose access to data if the Sun StorEdge T3 disk array are submirrors of each other.

  1. On one node attached to the Sun StorEdge T3 disk array you want to upgrade, detach that Sun StorEdge T3 disk array's submirrors.

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

  2. Apply the controller, disk drive, and UIC firmware patches.

    For the list of required Sun StorEdge T3 disk array patches, see the Sun StorEdge T3 Disk Tray Release Notes. For the procedure on applying firmware patches, see the firmware patch README. For the procedure on verifying the firmware level, see the Sun StorEdge T3 Installation, Operation, and Service Manual.

  3. Reset the Sun StorEdge T3 disk array, if you have not already done so.

    For the procedure on rebooting a Sun StorEdge T3 disk array, see the Sun StorEdge T3 Installation, Operation, and Service Manual.

  4. Reattach the submirrors to resynchronize them.

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

How to Replace a Disk Drive

Use this procedure to replace one failed disk drive in a Sun StorEdge T3 disk array in a running cluster.

Caution - Caution -

If you remove any field replaceable unit (FRU) for an extended period of time, thermal complications might result. To prevent this complication, the Sun StorEdge T3 disk array is designed so an orderly shutdown occurs when you remove a component for longer than 30 minutes. A replacement part must be immediately available before starting a FRU replacement procedure. You must replace a FRU within 30 minutes or the Sun StorEdge T3 disk array, and all attached Sun StorEdge T3 disk arrays, will shut down and power off.

  1. If the failed disk drive impacted the Sun StorEdge T3 disk tray logical volume's availability, remove the Sun StorEdge T3 disk tray logical volume from volume management control. Otherwise, proceed to Step 2.

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

  2. Replace the disk drive.

    For the procedure on replacing a disk drive, see the Sun StorEdge T3 Installation, Operation, and Service Manual.

  3. If you removed a LUN from volume management control in Step 1, return the LUN(s) to volume management control. Otherwise, Step 2 completes this procedure.

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

How to Add a Sun StorEdge T3 Disk Array

Use this procedure to add a Sun StorEdge T3 disk array to a running cluster. This procedure provides flexibility so you can either add a Sun StorEdge T3 disk array, a Sun StorEdge FC-100 hub and host adapters, or add a Sun StorEdge T3 disk array to an existing Sun StorEdge FC-100 hub and host adapters.

This procedure defines Node A as the node you want to begin working with, and Node B as the remaining node.
