We are not using NPIV anywhere. Linux Version is RedHat Enterprise Linux v6.1.
We have 2 VIO Servers i.e. VIO1 and VIO2 ( Same disk is getting visible to the OS from two different path coming from VIO1 and VIO2 ). When we shutdown one of the VIO Servers, RedHat root filesystem automatically mount itself into read-only mode and we receive I/O errors on OS and OS become unavailable.
Do we have any solution for redundacy of SCSI disk ( One disk ) coming from two VIO Servers. Or we need to manage this only using Software RAID on Linux.
As these are SCSI disk not directly coming through FC adapter, do we still need to configure Linux Mulitpath Driver.or this would be handled by ibmvscsi driver itself.
Any document or links which can guide us how to setup redundancy of SCSI disk in case of Power Linux.
