EMC problem?

Odd Olsson — Mon, 31 Jan 2005 16:44:03 GMT

We have an EMC array and having this error messages on the console during the reboot.

Starting EMC PowerPath
emcp:Mp:Error: All paths to Symm 000287750504 vol 015c are dead.

This repeats with different vol numbers 5 times totally.

We have 5 lunes from the EMC array.

Any Ide what this means.
It look like we have all this disc with us. (ioscan)
We have build volumes on them also.

Chers.

Odd,
It looks like this is complaining about the path. I would suggest that you reseat the links and try again as a first step.

Also check the status of the links using
'/opt/EMCpower/bin/powermt display'

Hi,
Use '/sbin/powermt check' and remove all dead device path.

For example:
#powermt check
Warning: Symmetrix device path c12t0d0 is currently dead.
Do you want to remove it (y/n/a/q)? y
Warning: Symmetrix device path c12t0d1 is currently dead.
Do you want to remove it (y/n/a/q)? y
Warning: Symmetrix device path c12t0d2 is currently dead.
Do you want to remove it (y/n/a/q)? y
