IBM Storwize V7000 Unified Problem Determination Guide

About this task
It might be necessary to service a node canister or to replace a part that is either a
customer replaceable unit (CRU) or a field replaceable unit (FRU) that is contained
within the canister. To remove the lid of a node canister, follow these steps.
Attention: The lid of a node canister can be removed only after the canister was
removed from its enclosure. Unless you are otherwise instructed, follow the
procedure for removing a node canister to remove a node canister from its
enclosure.
To remove a canister lid:
1. Place the node canister upside down on a work surface, with the release levers
facing toward you.
2. Open the cover of the canister by depressing the recessed, blue touch points on
the lid and sliding the lid away from you, as shown in Figure 78.
To replace a canister lid, slide the canister lid onto the canister until the catch clicks
and the lid edges are flush with the canister.
Procedure: Understanding Storwize V7000 Gen2 volume
dependencies
If one component in a redundant pair is offline or powered off, host access to
volumes depends on a Storwize V7000 Gen2 enclosure or canister in the system.
v If a control enclosure only has one node canister online, access to a volume
depends on the online node canister if the volume is stored partially or wholly
on an array that uses drives in the control enclosure or its expansion enclosures.
