Issue
-
Server works fine when it is loaded with this kernel parameter on grub - "rdloaddriver=scsi_dh_alua" on RHEL 6.4, but why this is needed when "RHEL 5" servers doesn't need this parameter.
-
Multipath issue after rebooting the hosts. Local vgoracle filesystems are getting corrupted and some of the ASM disks are missing.
