Hi,
we currently have an issue with an EVA 8400 and ESXi5 configured with VMW_SATP_ALUA and RR.
After the first scan of the FC Controllers the optimal paths are discovered - this is OK.
But, when the SAN admin changes the owning controller the esxi host does not automatically switch over to the new optimal paths.
So all IO is going through the mirror cache of the EVA.
Only after a rescan esxi finds the new optimal paths ? Is this how it should be ?
My understanding of SCSI-3 is that the host MUST switchover... even a simple linux system does so.
Please give me some help about this issue
THX
Alex
