Might be too late for RHEL5 but perhaps changing the max #define isn't out of the question. (Sanjay Gulabani at netapp asked for this - Sanjay.Gulabani) Here's the thread earlier this year with a patch that never got in upstream: http://tinyurl.com/wynfp Maybe we can resurrect something like that for upstream and long-term.
Ok I looked at the code in more detail and remember that it's probably not so easy to change the #define because of the structures we allocate based on these max values. I was going to reassign this to myself but it doesn't look like I can change the assignment field.
Reassigning to DaveW based on comment #2. Please fix the bug summary to contain something that can be found in the RHEL5 kernel source tree. ISCSI_MAX_CMDS_PER_LUN does not exist, and the place in RHEL4 where its use was converted to iscsi_cmds_per_lun, which was in the function iscsi_slave_configure(), doesn't exist in RHEL5.
Dave I can take this one if you want. It is all upstream in the open-iscsi git tree so it just requires a backport. I did not port this part in my 5.1 update because I did not have time to test the KABI and ABI workarounds that are needed to port upstream to RHEL.
Ok thanks - I am sure it would take me much longer to get it right.
This was fixed in RHEL 5.2 or RHEL 5.3. Closing bug.
