Recently I came across an issue. Could someone help me understand why that caused the
P770 running AIX with Pcmpath connected to IBM SAN Volume Controller. One of the path failed due to Node failure in SVC. during that period, the server was rebooted and the LUNs was visible after the reboot. But the VGs could not be varyed on.
Then the Volumes were pushed to the surviving node and the varyonvg worked.
What could be the reason for not having automatic switching when one of the path was unavailable after the reboot.
