Cause
Due to an OS requirement, the patches specified in KB article 000025503 use SCSI request_queue to send the SCSI commands to the underlying block device. An additional patch is required from EMC to support processing SCSI commands via the request_queue mechanism on EMC PowerPath devices. Failure to install the EMC patch can cause this issue.
Resolution
An additional patch is required from EMC to support processing SCSI commands via the request_queue mechanism on EMC PowerPath devices. These patches are specific to Linux kernel levels. Please contact EMC for the correct patch details.
Issue/Introduction
After upgrading Volume Manager to patches specified in KB article 000025503 (https://www.veritas.com/support/en_US/article.000025503), Volume Manager is not able to register SCSI-3 fencing keys and import shared disk groups on disks managed by EMC Powerpath.
