Hi,

In my hp-ux 11.11 system the following error message is comming

""""vmunix: AUTOPATH : Path 0xbc17e000 failed! Rerouting to alternate path
Aug 10 11:00:01 bkup vmunix: AUTOPATH : Path 0xbc18e000 failed! Rerouting to alternate path
Aug 10 11:00:02 bkup vmunix: AUTOPATH : Path 0xbc170300 failed! Rerouting to alternate path
Aug 10 11:00:02 bkup vmunix: AUTOPATH : Path 0xbc170300 recovered

Aug 10 11:00:02 bkup vmunix: AUTOPATH : Path 0xbc18e000 recovered""""""'

You have SAN connection via multiple path.
Because of some reason,primary paths are failed and AUTOPATH redirected the connections thru alternate path.ANd reverted back later.

Somebody might have pulled the fiber cable from server/SAN switch!!

Hi Arun,

Since the same paths (0xbc170300, 0xbc18e000) has been recovered, so the message is just a notification for you.

The SAN connection on your system have a multiple path with AUTOPATH setting if the path is failed.

You can check also on the event.log at /var/opt/resmon/log directory and 'ioscan -nf' command (see if there's NO_HW status on your system or not).

Hope this information can help.

Cheers,
AW

Regarding - Path 0xbc170300 recovered. Remove the 0xbc from the error message and grep for it.

# cd /dev/dsk
# ls -lrt | grep 170300

To find out the VG, run pvdisplay on the device file you get from the above command

# pvdisplay /dev/dsk/ | grep "VG"

the VG number it refers in the message must match the minor number of the group control file of the VG

# cd /dev
# find . -name group -exec ls -lrt {} \;

Since this appears to be vg00 verify with lvlnboot -v or strings /etc/lvmtab

Hi Arun,

Provide with more info.

It seems to be your one of the hostadapter connection with the storage is failed.You can find out the the device with major number in the dmesg.

Hi arun,

of course the message is written when the occurrence happens. The system doesn't check if the path is recovered later.
So the messages can appear within seconds or hours or days later.
I don't think that you want to stop these messages, it's a hint that something can be wrong with your SAN connections.
