Hi.
I have this problem: I have an IBM BLADECENTER, one of the blades with ESX 3.5 and a DUAL iSCSI HBA Controller, connected to IBM DS 3300 iSCSI storage with dual controller.
All this configured as follow.
Port A HBA - 192.168.3.60 > switch 1 > SPA_NIC1-192.168.3.53 - SPB_NIC1-192.168.3.55
Port B HBA - 192.168.4.61 > switch 2 > SPA_NIC2-192.168.4.54- SPB_NIC2-192.168.4.56
By this configuration I have four paths to the LUNS in the SAN.
Here is the problem.
If turn off the switch 1, emuling a break, the failover is succeed and the paths go through the switch 2. But, when the switch 1 is up again the paths still appears like DEAD.
This paths continues DEAD until I do a rescan.
This behavior is present on FIXED, MRU or RR policy.
I want to this path DEAD go back automatic to ON or ACTIVE when the switch 1 is up again.
The HBA is a Qlogic 40xx.
Maybe I am doing something wrong.
I appreciate your time.
