Unable to create a ISCSI Lun
I have a CLARiiON AX4-5F8 SL7F9104900012 2.23.50.5.709,6.23.8 (0.13
I recently added 6 X 2TB drives onto my system. I created a RAID 5 plus 1 HS. Then I create about 3 TB file system which I was able to do. After that I was ready to create the iSCSCI LUN. The toral space for this file system is 3210.181 GB. But, everytime I try to create a LUN I get the following error message. I am using EMC Unisphere:
"Create iSCSI Lun server_2:iscsi-tgt1:6. 3237064 MB is larger than the maximum LUN size allowed. detail". So, I have tried different number as low as 3000000 MB but I am getting the same error. Any ideas what I am doing wrong? Please see the attached files.

So this array is an NX4 (NAS) and you create a 3TB LUN and attempt to present to a host - what is the host? Some operating ssytems do not allow a 3TB LUN - Windows is 2TB limit.

Maximum iSCSI LUN size is 2TB-1MB (2,097,151 MB). See attached image which is from Unisphere Help.
