This section describes how to replace the storage module. A failed storage module is considered a FRU, and can only be replaced by a qualified Oracle technician.
The following rules apply when removing the storage module:
You must stop all I/O to storage module disks before attempting to remove the storage module. This must be done at the host at the operating system level by gracefully terminating applications and processes utilizing storage on the module. Since storage module resources can be divided among different hosts, this needs to be done at each host that uses storage on the storage module to be removed.
Caution - Removing the storage module before gracefully terminating host applications that are accessing storage module resources could cause data loss.
Before removing the storage module, ensure that you have a saved copy of the current CMM ILOM configurations. If not, you must save your current CMM ILOM configurations. You will need to login to the CMM to do this (look under the Maintenance tab). This will also save host-to-storage assignments which can then be restored if zoning assignments are lost.
When reinstalling the storage module, it must be installed in the same chassis slot it was removed from. This is critical in order for the server(s) that use storage on the module to see that storage when the module is reinstalled. For more on supported hot-plug actions, refer to the Sun Blade Storage Module M2 Administrator Guide.
Note - If you accidentally reinstall the storage module into a different chassis slot from the one it was in originally, zoning configurations saved on the storage module expanders will be erased and you will need to reconfigure or recover host storage assignments through the CMM ILOM. Refer to Recovering Zoning Configurations in Sun Blade Storage Module M2 Administration Guide for more information.
If you are replacing a failed storage module, be sure to move all disks to the new storage module. Disks should be placed into the new storage module in same slot order as they were in the old storage module.
Unless you plan on shutting down the entire blade chassis, have a filler panel ready for when you remove the storage module. Leaving an open slot in the chassis disrupts the proper air flow and will cause blades in the chassis to over heat.
