Q: 6 You are troubleshooting a clustered failover problem at a customer site. The customer explains that both storage appliances were NFS mounted onto the Solaris host. You attempt to create a file on the NFS mount point for the inaccessible appliance, but you get the following error:
NFS server filer2 not responding still trying.
1) When not in takeover mode, both storage appliances operate normally.
2) In takeover mode, the taken over node is not accessible on the network.
You perform a"cf giveback" and you can now create a file over NFS on both appliances. What should you do first to resolve this issue?
A. Replace the cluster interconnect card and run diagnostics "all"to ensure proper system operation.
B. Replace the NIC adapter.
C. Use the cluster-config-checker.cgi to identify the problem and corrective action.
D. Submit a new bug report.
Answer: C

Q: 7 Which of the following commands would you issue to perform a "clean" shutdown of a clustered system without allowing takeover to occur?
A. halt
B. halt -f
C. halt -d
D. sys-shutdown
Answer: B

Q: 8 A storage appliance in a clustered configuration can's access its partner's mailbox disks. When you enter the cf status command, you see the following:
filer2> cf status
filer1 is up, takeover disabled because of reason (partner mailbox disks not accessible or invalid)
What should you check first to resolve this issue?
A. Check volumes of all disks
B. Check NIC adapter
C. Check that initiator is set to "target"mode
D. Check for disk viability or FC-AL problems
Answer: D

Q: 9 If an error message indicates that the cluster interconnect adapter itself is faulty, what is your corrective action?
