Display differences between HSG80, HSV110/HSV100, and MSA1000
controllers
All general examples in this document use the MSA1000 serialization format and
actual MSA1000 examples. The HSG80, HSV110/HSV100, and MSA1000
present objects to Secure Path in identical ways. There is no difference in the way
you manage settings, paths, and devices using the spmgr management utility.
For the HSG80 and HSV110/HSV100, there are two differences in serialization of
array objects that allow you to quickly determine which type of array is being
displayed. The following examples list the differences:
HSG80
World Wide Node Name (WWNN): 5000-1FE1-0016-68C0
World Wide LUN ID(WWLUNID):
6000-1FE1-0016-68C0-0009-2040-0315-002E
Controller Serial Number: ZG20400315

Degraded At least one or more paths are failed to the storage unit.
Operational All paths are available to the storage unit.
Unknown Unable to communicate with the unit. This may indicate no
available path or a failed device.
Failed Paths are available but an inquiry to the device returns a
not-ready state even after retries.
