Hi, # mkinitrd -f /boot/initrd-`uname -r`.img `uname -r` Created the new mkinitrd ; still facing the same issue. No luck. We are using LUNs from EMC CLARiiON frame. Since we are not SAN booting; I guess all that I have to do is install powerpath, discover the LUN allocated and put it to use with regular lvm commands. I am not sure what SAN drivers needs to be loaded before automount and if they have to be included in initrd-2.6.18-238.el5.img. We use emulex fibre adapters. I am also not sure if this has anything to do with the settings for HBA. # powermt display dev=all Pseudo name=emcpowera CLARiiON ID=APM11105711783 [zlnx_009] Logical device ID=711711615C54231128C4C83E26D3E111 [Lun 0611] state=alive; policy=CLAROpt; priority=0; queued-IOs=0; Owner: default=SP B, current=SP B Array failover mode: 1 ============================================================================== --------------- Host --------------- - Stor - -- I/O Path -- -- Stats --- ### HW Path I/O Paths Interf.
