Obviously you will want whatever you saw in the previous step, but in case you plan on using some other configurations, you can add everything from the list from above. I always do it before I build a cluster. Now, the only thing about this is that I have never tried this after I had built a cluster.
Driver needed during upgrade to r2 (DGC Raid 5 Scsi)
Your registration case number is: Yes you are right this needs to be done before creating cluster but in my case somehow we missed this thing. The "-n" switch suppresses the automatic reboot. Cheers Cheers Message was edited by: A SCSI-3 SCC-2 term defined as "the logical unit number that an application client uses to communicate with, configure and determine information about an SCSI storage array and the logical units attached to it.
Friday, September 7, 4: Without the LUNZ devices, there would be no device on the host for Navisphere Agent to push the initiator record through to the array.
Raif summary, this occurs because the arraycommpath setting of 1 creates a virtual LUN 0 for communication with the storage system.

The agent then communicates through the storage device. You may also refer to the English Version of this knowledge base article for up-to-date information. I have installed naviagent 6. This is mandatory for the host to log in to the Storage Group. Go to original post.
In the CLARiiON context, LUNZ refers to a fake logical unit zero presented to the xevice to provide a path for host software to send configuration commands to the array when no physical logical unit zero is available to the host.
High Availability Clustering https: I am using the same method as in my other working installs. Anytime you have system presented to a storage group that does not have a risk at Host Id Rescanning for new disks does not do anything either.
Best practice when adding EMC CLARiiON luns to a StorageGroup (handling of LUNZ devices)
However, Powerpath does not detect anything at all. May 15, 2: Now you can add the devoce support for the speicifc IDs you want.
Not an IT pro? It is just creating mulitple paths to the data. Sign in to vote. Configure hardware for Cgc. When I reboot the hardware wizard pops up and asks me to install multi-path support software. It almost seems like the unreadable is a ghost entry.
For help type inq -h. Repeat that commnd for each all device IDs desired.
Sdsi order for a host to register successfully a special "LUNZ" device must be successfully presented to the host for every path that is zoned to the array. If you require immediate assistance, please call us and we would be happy to assist.
