Verifying installation with storage arrays
-
Checking for back-end configuration errors preventing system operation
- The storage errors show messages and their resolution
- Array LUN size is either smaller or larger than the supported values
- LUN IDs for the same LDEV do not match
- Volume Set Addressing is inconsistent
- Duplicate LUN IDs on a target port
- Fewer than two paths to an array LUN
- An access control LUN is presented to ONTAP
- All paths to an array LUN are on the same storage array controller
- Array LUNs are configured with conflicting failover modes
- Array LUN is marked foreign and has a reservation
-
Verifying that the back-end configuration matches the intended configuration
- Reasons for no LUNs in the array LUN group
- Reasons for fewer array LUN groups than expected
- Reasons for more array LUN groups than expected
- Reasons for more paths to an array LUN than expected
- Reasons for the incorrect number of LUNs in array LUN groups
- Reasons storage arrays are missing from command output
