A customer wants to use SAN Copy to migrate data from their DMX to a new CLARiiON.
Zones have been created between the DMX FA port and the CLARiiON SP port. The host that owns the source volume only has storage allocated from the DMX; the Navisphere
Agent is installed and working properly. The source host is not visible when trying to create the session within the SAN Copy wizard. What can the customer do to resolve this issue?

  • A. Restart the Navisphere Agent on the source host. After the host registers, enter the host IP address directly into the SAN Copy session.
  • B. Retrieve the DMX FA port WWN and enter it directly into the SAN Copy session.
  • C. Retrieve the DMX volume WWN and enter it directly into the SAN Copy session.
  • D. Zone the DMX FA port to both CLARiiON SPs.

A customer has recently decommissioned a server and has decided to reuse it for another purpose in a new data center. Due to a high priority business request, the server is moved over and the operating system has not been reinstalled.
As the storage administrator, you attach the server via Fibre Channel to a new set of switches and a new CLARiiON. After attaching the Fibre Channel cables and performing the zoning, the host is not seen in the Connectivity Status screen on the new CLARiiON. A double check of the configuration reveals the zoning is correct and is not the problem.
What is the cause of the problem?

  • A. The failovermode has not been updated
  • B. The lpfc.conf has not been updated
  • C. The navimon.cfg has not been updated
  • D. The PowerPath configuration has not been updated

750 IOPS and tests will run for 24 hours. The customer would like to use a snapshot for this activity.
The customer has written a script using SNMP traps to check for free space prior to the start of the snapshot session. What specifically needs to be checked?

  • A. The clone Private LUN Pool will need to be approximately 2.1 times the size of the production LUN.
  • B. The free space in the Source RAID group will need to be 2.1 times the size of the production LUN.
  • C. The Reserved LUN Pool will need to be approximately 1.1 times the size of the production LUN.
  • D. The Reserved LUN Pool will need to be approximately 2.1 times the size of the production LUN.


Answer : D

A customer was migrating an application LUN to a LUN owned by the peer SP. Halfway through the migration the peer SP fails. What is the impact on the migration?
