Your customer has a Symmetrix DMX 1000 and wants to implement ILM. To get started on
ILM, your customer bought a CLARiiON CX500 with SAN Copy. Some systems have to be offloaded from the Symmetrix to the CLARiiON using SAN Copy. With the migration of the first system, the Symmetrix devices cannot be selected as a SAN Copy source. Which steps must be taken to correct the problem?

  • A. Verify cabling, verify zoning, the initiator has logged in, verify LUN masking, verify volume mapping, verify Navisphere agent on the host connected to the CLARiiON, verify the portal configuration in Navisphere
  • B. Verify cabling, verify zoning, the initiator has logged in, verify LUN masking, verify volume mapping, verify Navisphere agent on the host connected to the Symmetrix, verify the portal configuration in Navisphere
  • C. Check SP error log, verify cabling, verify zoning, the initiator has logged in, verify LUN masking, verify volume mapping, verify Navisphere agent on the host connected to the CLARiiON, verify the portal configuration in Navisphere
  • D. Check SP error log, Verify cabling, verify zoning, the initiator has logged in, verify LUN masking, verify volume mapping, verify Navisphere agent on the host connected to the Symmetrix, verify the portal configuration in Navisphere


Answer : B

NLP Farm, Inc wishes to use SAN Copy to transfer data between CLARiiONs at two sites.

  • A. Change the initiator type to P No Auto Trespass?&KDQJHWKHLQLWLDWRUW\SHWR?31R$XWR7UHVSDVV
  • B. Remove ptionsSupported AutoTrespass?from the agent.config file, add oMegaPoll?in it, and restart the agent
  • C. Run the following commands for every CLARiiON LUN in question: scsictl -a /dev/rdsk/cxtydz scsictl -a -m queue_depth=4 -m queue_depth /dev/rdsk/cxtydz
  • D. Create a script with the following commands for every CLARiiON LUN in question and allow it to run after every system start: scsictl -a /dev/rdsk/cxtydz scsictl -a -m queue_depth=4 -m queue_depth /dev/rdsk/cxtydz
