• GBIC on an FC switch, connecting to a storage array

• FC switch

Step

Replace the component by using the following references.

• For the procedure about how to replace a fiber-optic cable between a storage array and an FC switch, see the documentation that shipped with your switch hardware.

• For the procedure about how to replace a GBIC on an FC switch, see 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. 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.
