Procedure
Complete the following steps to understand when a node canister is not
participating in the system, and what remedial action to take.
1. Identify the control enclosures for the system you are troubleshooting.
To understand which are the control enclosures, refer to the topic about
identifying the Storwize V7000 2076-524 enclosure or canister to service.
2. Use Table 88 to check the status of each power supply unit (PSU) in a control
enclosure.
3. If at least one PSU is providing power to a control enclosure, use Table 89 on
page 258 to check the status of each node canister in that enclosure.
