Unable to mount path from SAN
 

I have attach the linux server to the SAN storage as below , all the path from the SAN can be mount but except /dev/emcpowerf1 is not mount, I sure this path (/dev/emcpowerf1) is available , the error as below , can advise what is the possible reason of it ?


#/etc/fstab
/dev/emcpowerb1 /mnt/c1 ext3
/dev/emcpowerc1 /mnt/c2 ext3
/dev/emcpowerd1 /mnt/c3 ext3
/dev/emcpowere1 /mnt/c4 ext3
/dev/emcpowerf1 /mnt/c5 ext3
/dev/emcpowerg1 /mnt/c6 ext3
/dev/emcpowerh1 /mnt/c7 ext3
/dev/emcpoweri1 /mnt/c8 ext3


#mount /dev/emcpowerf1 /mnt/c5
mount: /dev/emcpowerf1 is not a valid block device

At first glance it looks like /dev/emcpowerf1 was not formatted as ext3. If this is not the case, and you have PowerPath/Naviclnt installed, run the naviserverutilcli to make sure the LUN is presented to the system from the EMC san.
