Sun Cluster 3.0-3.1 With Sun StorEdge T3 or T3+ Array Manual for Solaris OS

Upgrading Sun StorEdge T3 or T3+ Storage Arrays

This section contains the procedures about how to upgrade storage arrays. The following table lists these procedures.

Note –

When you upgrade firmware on a storage device or on an enclosure, redefine the stripe size of a LUN, or perform other LUN operations, a device ID might change unexpectedly. When you perform a check of the device ID configuration by running the scdidadm -c command, the following error message appears on your console if the device ID changed unexpectedly.


device id for nodename:/dev/rdsk/cXtYdZsN does not match physical 
device's id for ddecimalnumber, device may have been replaced.

To fix device IDs that report this error, run the scdidadm -R command for each affected device.

ProcedureHow to Upgrade Storage Array Firmware (No Submirrors)

Use this procedure to upgrade storage array firmware in a running cluster, when your arrays are not configured to support submirrors. To upgrade firmware when you are using submirrors, see How to Upgrade Storage Array Firmware When Using Mirroring. Firmware includes controller firmware, unit interconnect card (UIC) firmware, and disk drive firmware.

Caution – Caution –

Perform this procedure on one storage array at a time. This procedure requires that you reset the storage arrays that you are upgrading. If you reset more than one storage array at a time, your cluster loses access to data.

Note –

For all firmware installations, always read any README files that accompany the firmware patch for the latest information and special notes.

Steps

  1. On one node that is attached to the storage array, detach the submirrors. This storage array is the storage array that you are upgrading.

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

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

    For the procedure about how to reboot a storage array, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.

  4. Reattach the submirrors to resynchronize the submirrors.

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

ProcedureHow to Upgrade Storage Array Firmware When Using Mirroring

Use this procedure to upgrade out-of-date controller firmware, disk drive firmware, or unit interconnect card (UIC) firmware. This procedure assumes that your cluster is operational. This procedures defines Node A as the node on which you are upgrading firmware. Node B is another node in the cluster.

Caution – Caution –

Perform this procedure on one storage array at a time. This procedure requires that you reset the storage arrays that you are upgrading. If you reset more than one storage array at a time, your cluster loses access to data.

Steps

  1. On the node that currently owns the disk group or diskset to which the mirror belongs, detach the storage array logical volume. This storage array is the storage array on which you are upgrading firmware.

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

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

    For the list of required storage array patches, see the Sun StorEdge T3 Disk Tray Release Notes. For the procedure about how to apply firmware patches, see the firmware patch README file. For the procedure about how to verify the firmware level, see the Sun StorEdge T3 Disk Tray Release Notes.

  3. Disable the storage array controller that is attached to Node B. Disable the controller so that all logical volumes are managed by the remaining controller.

    For more information, see the Sun StorEdge T3 and T3+ Array Administrator's Guide.

  4. On one node that is connected to the partner group, verify that the storage array controllers are visible to the node.

  5. Enable the storage array controller that you disabled in Step 3.

  6. Reattach the mirrors that you detached in Step 1 to resynchronize the mirrors.

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

ProcedureHow to Upgrade a StorEdge T3 Controller to a StorEdge T3+ Controller

Use the following procedure to upgrade a StorEdge T3 storage array controller to a StorEdge T3+ storage array controller in a running cluster.

Caution – Caution –

Perform this procedure on one storage array at a time. This procedure requires you to reset the storage arrays that you are upgrading. If you reset more than one storage array at a time, your cluster loses access to data.

Steps

  1. On one node that is attached to the StorEdge T3 storage array in which you are upgrading the controller, detach that storage array's submirrors.

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

  2. Upgrade the StorEdge T3 storage array controller to a StorEdge T3+ storage array controller.

    For instructions, see the Sun StorEdge T3 Array Controller Upgrade Manual .

  3. Reattach the submirrors to resynchronize the submirrors.

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

ProcedureHow to Migrate From a Single-Controller Configuration to a Partner-Group Configuration

Use this procedure to migrate your storage arrays from a single-controller (noninterconnected) configuration to a partner-group (interconnected) configuration. This procedure assumes that the two storage arrays in the partner-group configuration are correctly isolated from each other on separate FC switches. Do not disconnect the cables from the FC switches or the nodes.

Caution – Caution –

You must be a Sun service provider to perform this procedure. If you need to migrate from a single-controller configuration to a partner-group configuration, contact your Sun service provider.

Steps

  1. Back up all data on the storage arrays before you remove the storage arrays from the Sun Cluster configuration.

  2. Remove the noninterconnected storage arrays to be in your partner group from the cluster configuration.

    Follow the procedure in How to Remove a Partner Group.

  3. Connect and configure the single storage arrays to form a partner group.

    Follow the procedure in the Sun StorEdge T3 and T3+ Array Field Service Manual.

  4. Ensure that each storage array has a unique target address.

    For the procedure about how to verify and assign a target address to a storage array, see the Sun StorEdge T3 and T3+ Array Configuration Guide.

  5. Ensure that the cache and mirror settings for each storage array are set to auto.

  6. Ensure that the mp_support parameter for each storage array is set to mpxio.
