Identifying and locating the faulted part in Unisphere Before you replace a faulted part, locate its placement within the storage system. Steps 1. In Unisphere, select System View. 2. Select the Enclosures page. 3. Locate the faulted part marked orange, and displayed in the Enclosures view. Preparing the SP assembly for service About this task 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. NOTE: Do not add or reseat NVMe Flash drives when the system is in the reset and hold state. Steps 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 > Alerts. 5.

Preparing the SP assembly for service
About this task
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.
NOTE:
Do not add or reseat NVMe Flash drives when the system is in the reset and hold state.
Steps
1.
Open Unisphere and select
Service
, then
Service Tasks
