Got a strange problem:
After enabling Performance Monitoring on CAM, I get no performance stats on Volumes mapped to Controller B.
On Controller Summary -> View Performance Statistics:
A 26.20 141.99 5.97 94.02 296.05 KBps 12.64 KBps 1790.72 KBps 12544.90 KBps 283.41 KBps 1283.03 KBps 6303.60 KBps 11.56 KB 74.51 KB 100.00
B 0.00 0.00 0.00 0.00 0.00 KBps 0.00 KBps 0.00 KBps 0.00 KBps 0.00 KBps 0.00 KBps 0.00 KBps 0.00 KB 0.00 KB 0.00
Is there any way to correct this problem? Maybe a Ctrl B reboot?
Array Communication Test passes OK for both ctrlers.
This is related to the bug 15654610 fixed in CAM 6.8 and higher.
Upgrade to CAM 6.8 or higher (the latest is 6.9 + patches).
Assign the volumes to controller A and collect the statistics. You likely registered the array with the controller A IP, due to this bug, the statistics are not returned by the controller A for the volumes owned by B.
