Re: About SAN server

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..
