How to Replace a Hub, Switch, or Hub/Switch-to-Array Component

Use this procedure to replace a hub, switch, or the following hub/switch-to-array components. (StorEdge T3/T3+ arrays in single-controller configuration can be used with StorEdge Network FC Switch-8 or Switch-16 switches when creating a SAN.)

• Fiber-optic cable that connects a hub/switch to a StorEdge T3/T3+ array

• FC-100 hub GBIC that connects a hub to a StorEdge T3/T3+ array

• Sun StorEdge FC-100 hub

• Sun StorEdge FC-100 hub power cord

• Media interface adapter (MIA) on a StorEdge T3 array (not applicable for StorEdge T3+ arrays)

1. Detach the submirrors on the StorEdge T3/T3+ array that is connected to the hub/switch-to-array fiber-optic cable you are replacing in order to stop all I/O activity to this StorEdge T3/T3+ array.

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

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

   • For the procedure on replacing a fiber-optic cable, see the Sun StorEdge T3 and T3+ Array Configuration Guide.

   • For the procedure on replacing an FC-100 hub GBIC, a Sun StorEdge FC-100 hub, or a Sun StorEdge FC-100 hub power cord, see the FC-100 Hub Installation and Service Manual.

   • For the procedure on replacing 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 Sun StorEdge Network FC Switch-8 and Switch-16 Installation and Configuration Guide, Sun SAN 3.0.

     Note -

     If you are replacing an FC switch and you intend to save the switch IP 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 saving and recalling switch configurations see the Sun StorEdge Network FC Switch-8 and Switch-16 Installation and Configuration Guide, Sun SAN 3.0.

     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. Increasing the value of the probe_timeout parameter to more than 90 seconds avoids unnecessary resource group restarts when one of the FC switches is powered off.

3. Reattach the submirrors to resynchronize them.
