Preparing the storage processor (SP) for service
To protect your system from accidental data loss during this maintenance activity,
prepare the SP for service. You prepare the SP for service by putting it in Service
Mode.
Entering Service Mode stops I/O on the SP so that service tasks can be safely
performed.
Note
Both SPs must NOT be in Service Mode at the same time.
Procedure
1. Open Unisphere and select Service, then Service Tasks.
2. Under the name of the storage processor where you will install the new part,
select Enter Service Mode and then click Execute.
3. When prompted, enter the Service Password to put the SP into Service Mode.
4. (Optional) Either refresh your browser or follow the on-screen instructions to
restore full-functionality to Unisphere.
When placing the primary storage processor into Service Mode, Unisphere will
become momentarily unresponsive (about one minute) as the management
services transfer over to the other SP.
5. Return to cabinet with the system and locate the SP in the DPE from the back
of the cabinet.
6. Wait until the SP fault LED is flashing alternating amber and blue before
continuing to the next task.
The SP fault LED will flash alternating amber and blue while the SP remains in
Service mode and is receiving active power.
