問題 #4

You are troubleshooting a clustered failover problem at a customer site. The customer explains that both storage systems were NFS mounted onto the Solaris host. While in takeover mode, you attempt to create a file on the NFS mount point for the inaccessible system, but you get the following error:
NFS server filer2 not responding still trying.
When not in takeover mode, both storage systems operate normally and you do not get the error. You perform a "cf giveback" and you can now create a file over NFS on both systems. 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. Submit a new bug report.
C. Use the cluster-config-checker.cgi to identify the problem and corrective action.
D. Replace the NIC adapter.
