While mapping devices to FA's same available lun address has to be taken on both direcotor's or we can take anything.
on director 10A port 0 lun address "03F" is availabe,but it is not available on director 7A port 0.
Can i take '03F' for director 10A port 0 and '08D' for director 7A port 0...?
is it mandatory to take same lun address on both directory's for same devices..?
Thanks in advance.
Solved! Go to Solution.
If the 03f is not available on the FA's that you want to use, then you cannot take it.
Using the SMC, when you are trying to map a device to two or to four FA's, you are able to see what address the SMC "serves" to you.
If you click on the button APPLY, which is at the right down corner, then SMC serves to you the SAME lun address for your device.
It is mandatory to have the same Lun address, devices that will be provisioned for ESX for sure.
If i remember well devices that are going to be provisioned to a Windows Cluster must have the same LUN address.
For Open systems as fas as i know it is not mandatory.
Windows Clusters do not need the same LUN address. Windows uses either disk signatures or GUIDs.

actually on director 10a port 0 device 21BF is already provisioned with lun address 03f.
now i have to configure for director 7a port 0 for redundancy .
On director 7a port 0 lun address 03f is not available to map the device.
So can i map the device 21BF on director 7a port 0 with available lun address or i have to use same lun address which is used for director 10a port 0.
i know 03f is cant be utilized on director 7a port 0 b'cause it was already utilizing by another device.
if same lun address has to be used on both director's means will lun offset helps me or is there any other option to get out of this.
So can i map device 21BF on director 7a port 0 with available lun address irrespective of what is used for director 10a port 0 .
And on director 10a port 0 device is already utilizing by Solaris server. So this mapping can be done online, or it requires any downtime of server.Because this is very critical server.
Thanks in Advance.
