fail to mount a path in SAN

I have newly setup the LUN in EMC server, the below is the output of "powermt display dev=all" ,

Pseudo name=emcpowera
CLARiiON ID=CK2000686974684 [A 1]
Logical device ID=60060160CBB1180064B21FTWZ50DCDB11 [LUN 1]
state=alive; policy=CLAROpt; priority=0; queued-IOs=0
Owner: default=SP A, current=SP A
==============================================================================
---------------- Host --------------- - Stor - -- I/O Path - -- Stats ---
### HW Path I/O Paths Interf. Mode State Q-IOs Errors
==============================================================================
2 QLogic Fibre Channel 2300 sde SP B0 active alive 0 0
3 QLogic Fibre Channel 2300 sdj SP A0 active alive 0 0

It seems normal , but when I try to mount it , it pop the messages , can advise what is wrong in my setting ? thx

mount -t ext3 /dev/emcpowera1 /emc1
mount: wrong fs type, bad option, bad superblock on /dev/emcpowera1,
or too many mounted file systems
(could this be the IDE device where you in fact use
ide-scsi so that sr0 or sda or so is needed?)

Shalom,

The -t ext3 is not needed because the mount command can figure out this on its own. This is the default mount type.

If you have not run newfs or mkfs.ext3, you can't mount the SAN based filesystem.

Re: fail to mount a path in SAN

Hi,

as SEP said, you have to create a filesystem (format de disk) before mount it.

Did you ?
