It is possible to reconfigure one node canister of each control enclosure at the same time. During the procedure, both I/O groups (control enclosures) are online with no redundancy, but the total maintenance period is reduced.
To replace host interface adapters in both control enclosures concurrently, use the procedure for replacing the host interface adapter in a single enclosure, but complete each step in both enclosures before continuing to the next step. Table 1 shows how to sequence the step in each node. Work your way down the table, completing each row before starting the next row.
For the procedure for replacing the host interface adapter in a single enclosure, refer to the Replacing a Lenovo Storage V7000 Gen2 host interface adapter.
