Workaround
Known workarounds for this issue are:
- Use the 64-bit version of Novell Open Enterprise Server 2, rather than the 32-bit version.
- Use of device-mapper multipath I/O (DM-MPIO) instead of EMC
PowerPath. DM-MPIO is supported by Novell Technical Services and
EMC both.
Additional Information
Status
At this time, this error has been reported only for 32-bit Linux running PowerPath; it has been reported that running 64-bit OES 2 Linux does not have this problem. If possible, running 64-bit OES2 Linux may resolve this problem.
For information on setting up DM-MPIO on OES 2, please see the SLES 10 Storage Administration Guide.This documentation refers to using "/dev/disk/by-id". While this will work, Novell NTS is recommending using "/dev/disk/by-name" instead.

Novell has
contacted EMC in regards to this matter. At the time of the writing
of this TID, EMC had not certified OES 2 Linux for use of
PowerPath. EMC considers OES 2 to be an add-on product and has
certified SUSE Linux Enterprise Server 10 SP1 for
PowerPath.
