Preliminary Information for Replacing SPARCstorage Array Components

The SPARCstorage Array components that can be replaced include the disks, fan tray, battery, tray, power supply, backplane, controller, optical module, and fibre channel cable.

Some of the SPARCstorage Array components can be replaced without powering down the SPARCstorage Array. Other components require the SPARCstorage Array to be powered off. Consult the SPARCstorage Array documentation for details.

To replace SPARCstorage Array components that require power off without interrupting services, you perform the steps necessary for tray removal for all trays in the SPARCstorage Array before turning off the power. This includes taking submirrors offline, deleting hot spares from hot spare pools, deleting state database replicas from drives, and spinning down the trays.

After these preparations, the SPARCstorage Array can be powered down and the components replaced.

Because the SPARCstorage Array controller contains a unique World Wide Name, which identifies it to Solaris, special procedures apply for SPARCstorage Array controller replacement. Contact your service provider for assistance.
