We have SAN CX300 which attached to the linux server , after re-boot these two servers , I use the below command and found the below result , I have already start Powerpath , navisphere , the qla logic card is also started ( known from server log ) , can advise how can I attach it again ?
#/sbin/powermt display dev=all Device(s) not found.
you are probably better off searching for answers in an EMC forum but here is a place to start.
1) powermt is an EMC multipath solution, i believe there is a discover/scan option to this command ( read the user guide).. the luns just may need discovered again. if not.. 2) switches zones properly ? 3) lun masking correct ? 4) fiber channel cabled properly.
you will need to either work your way forwards or backwards through this list..
