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

ProcedureHow to Replace a Hub/Switch or Hub/Switch-to-Array Component in a Single-Controller Configuration

Use this procedure to replace a hub/switch or the following hub/switch-to-array components for an array in a single-controller configuration. To replace these components for an array in a partner-group configuration, see How to Replace an FC Switch or Storage Array-to-Switch Component in a Partner-Group Configuration. You can use storage array in single-controller configuration with FC switches when you create a SAN.

Steps

  1. Detach the submirrors on the storage array. This array is connected to the hub/switch-to-array fiber-optic cable that you are replacing. Detach the submirrors to stop all I/O activity to this storage array.

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

  2. Replace the hub/switch or hub/switch-to-array component.

    • For the procedure about how to replace a fiber-optic cable, see the Sun StorEdge T3 and T3+ Array Configuration Guide.

    • For the procedure about how to replace an FC hub/switch GBIC or an SFP, an FC hub/switch, or an FC hub/switch power cord, see the documentation that shipped with your FC hub/switch hardware.

    • For the procedure about how to replace an MIA, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.

    • If you are replacing FC switches in a SAN, follow the hardware installation and SAN configuration instructions in the documentation that shipped with your switch hardware.

      Note –

      If you are replacing an FC switch and you intend to save the switch configuration for restoration to the replacement switch, do not connect the cables to the replacement switch until after you recall the Fabric configuration to the replacement switch. For more information about how to save and recall switch configurations, see the documentation that shipped with your switch hardware.

      Note –

      Before you replace an FC switch, be sure that the probe_timeout parameter of your data service software is set to more than 90 seconds. If you increase the value of the probe_timeout parameter to more than 90 seconds, you avoid unnecessary resource group restarts. Resource group restarts occur when one of the FC switches is powered off.

  3. Reattach the submirrors to resynchronize the submirrors.

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