Question #4 (Topic: Topic 0)
A customer has two 50 GB MirrorView/S mirrored LUNs between two CX3-40s without a
Write Intent Log. LUN1 is on SP A and LUN2 is on SP B. The two CX3-40s are connected
via dedicated Fibre Channel links.
During the nightly maintenance window, the connection between SP A on the local array
and SP A on the remote array is lost for 2 minutes. SP B is unaffected. When the customer
logs in the next morning, they notice that LUN1 has a status of "attention" and is still
fractured.
What caused this behavior?

Question #5 (Topic: Topic 0)
A storage administrator has attached a HP-UX host to a CLARiiON environment consisting
of three CLARiiON arrays. The HP-UX host has six HBAs installed. The administrator will
not be using PowerPath as the failover software.
The administrator has run the following command to add a path from an HBA to the storage
group for the server:
naviseccli address cx1-spa storagegroup etpath name HPUX1 bauid
20:00:00:E0:8B:13:6A:92:21:00:00:E0:8B:13:6A:92 p a pport 0 ip 10.10.11.134 ost HPUX1-
failovermode 3 rraycompath 0
The command completes successfully; however, the host is not showing the devices when
oscan is run. How can the storage administrator fix this error?
