what did you use in fstab ..native /dev/sd* device or powerpath device ? You need to use powerpath device as that will not change at reboot time.

hi:

I used the powerpath device... /dev/emcpowerc...

any other clue?

thanks.

subject mount point is /dev/emcpowera /myfs1


/dev/cciss/c0d0p1 / ext3 acl,user_xattr 1 1
/dev/cciss/c0d0p2 /boot ext3 acl,user_xattr 1 2
/dev/cciss/c0d0p4 /local ext3 acl,user_xattr 1 2
/dev/cciss/c0d0p3 swap swap pri=42 0 0
/dev/emcpowera /myfs1 ext3 defaults 0 0
devpts /dev/pts devpts mode=0620,gid=5 0 0
proc /proc proc defaults 0 0
usbfs /proc/bus/usb usbfs noauto 0 0
sysfs /sys sysfs noauto 0 0
/dev/dvd /media/dvd subfs fs=cdfss,ro,procuid,nosuid,nodev,exec,iocharset=utf8 0 0
/dev/fd0 /media/floppy subfs fs=floppyfss,procuid,nodev,nosuid,sync 0 0

yes, the powermt display dev=all stay same..

mounting manually is fine. but once rebooted it is gone again.

but after reboot powerpath device name stayed the same ..and you can mount it manually ok ?

can you post content of /etc/fstab

found might could be cause of the problem..

when i run powermt display dev=all.. after another reboot
I found out I'm missing the clarion ID [server name] and the logical device [lun11]

what I did run again the powermt config and then run powermt save..
when I run the powermt display dev=all this time.. it looks good, I can see my server name and the LUN11.. however after the reboot the information is missing again the server name and logical device [lun 11].

anything suspicious in /var/log/messages ?

Go this specific to emcpowera..
It is confirmed, I'm lossing the powerpath config settings specific to LUN name and server name whenever I did reboot..
