A two-node Pacemaker cluster uses a GFS2 filesystem on shared storage. The cluster is experiencing lock contention issues, and the administrator suspects that the DLM is not functioning correctly. Which diagnostic step should be taken first?

Reconfigure the GFS2 filesystem with a different lock table name.

Reboot both nodes to reset the DLM state.

Increase the DLM lock timeouts in /etc/dlm/dlm.conf.

Check the status of the DLM resource in Pacemaker and verify that it is running on both nodes.

An administrator is setting up an iSCSI target for a database server that requires high availability. The target will be accessed by two initiators for multipath. The administrator wants to ensure that only these two initiators can access the LUN, and that they use CHAP authentication. Which configuration steps are required?

Use the 'allow' command to permit the two initiators and disable CHAP.

Create ACLs for both initiator IQNs and configure CHAP authentication on the target.

Configure CHAP authentication on the initiators only, not on the target.

Create a single ACL that allows all initiators and rely on CHAP to restrict access.

A storage administrator is troubleshooting a Fibre Channel connection between a server and a SAN switch. The server's HBA has a WWPN of 10:00:00:00:c9:2b:5a:11. The switch shows the port as 'No_Light'. What is the most likely cause?

The HBA driver is not loaded on the server.

The HBA is not properly zoned on the switch.

The optical cable or SFP is faulty or not connected.

The WWPN is not registered with the name server.
