Reset and hold is a special state during which power is maintained to the SP assembly
so that I/O modules, embedded modules, and 4-port cards can be safely removed.
This state has fewer management capabilities than Service Mode, but allows for easier
I/O module, embedded module and 4-port card replacement.
Note
Both SP assemblies must NOT be in reset and hold simultaneously. The system should
be up for at least 40 minutes since its last reboot before being placed into reset and
hold.
Procedure
1. Open Unisphere and select Service, then Service Tasks.
2. Under the name of the SP assembly where you will install the new I/O module,
embedded module or 4-port card, select Reset and Hold and then click
Execute.
3. When prompted, type the service password to put the SP assembly into reset
and hold.
4. (Optional) Either refresh the browser or follow the onscreen instructions to
restore full-functionality to Unisphere.
When placing the primary storage processor into hold in reset, Unisphere
becomes momentarily unresponsive as the management services transfer over
to the other SP. After about 10 minutes, the SP assembly's status will change
to Degraded, and indicate that the SP assembly has been placed in held in reset.
The SP assembly's status can be confirmed by checking the log entries in
Unisphere under Events
5. Wait until the SP assembly fault LED and power indicator LED are lit solid amber
and green, respectively, and the peer SP assembly's Unsafe to Remove LED is
lit before moving to the next task.
Use the fault LEDs to identify the faulted part.
