We have installed RHEL 4 and have configured diskdump to save a vmcore on SAN devices connected through Qlogic FC HBAs, but the diskdump is unable to save vmcore.
diskdumpservice is started manually then it fails with following error:
$ service diskdump restart diskdump: diskdumpctl: failed to add /dev/sdb1! diskdump: activating failed kernel: disk_dump: shut down
The same error messages are observed while trying to save vmcore on SAN devices connected through Emulex FC HBAs.
