I have two T2000 servers connected to sun storage array StorEdge 3310 as follows:
I have created some luns which I can mount and use on HOST1 but from HOST2 I cant see them
from OK prompt or from format utility. I do see them from sccli utility on HOST2 .
iam runnng solaris 10u11 with latest patches applied and both systems are identical.
the channel assignment on the storage array is as follows :
Chl Mode PID SID
0 Drive 6 7
1 Host 0 NA
2 Drive 6 7
3 Host 0 NA
6(c) RCCOM NA NA
this is what i get on HOST1
---------------------------
this is what i get on HOST2
---------------------------
NOTE: i just swapped the SCSI cables between HOST1 and HOST2 and now HOST2 can see all the LUNs and HOST1 can't which tells me that hardware and software wise everything is ok on HOST2
it has to do with some SCSI channel mappings and conflict , need help in debugging this .
Basically any host connected to CH3 is not seeing the disks. it does see the controller though .

I found the problem .
The mapping for luns for CH3 were missing . after adding the mapping both hosts can see the luns now.
