1A 1B72 4B EC31
1B 1B73 8B EC71
Total of 86 Luns are presented to NSC55 from 9570 from all the ports of each controller. From SAN health report i could found that only two
path are utilizing more ( EX more then 100 MB of data ) remaining two paths re utilizing less ( EX. 11 MB )
Customer is facing slow backup issue.
Now i would like to do the LUN balancing through universal volume manager of NSC. One of our senior engineer has suggested to do the
In the current case, if you observe only one port per controller being used.
1) Identify the External LUNs owned by controller 0 ( Identfied )
2) Reconfigure those LUNs in NSC-UVM; make 0A as priority path for half and 0B as priority path for remaining half (At NSC UVM)
3) Identify the External LUNs owned by controller 1 ( Identfied )
4) Reconfigure those LUNs in NSC-UVM; make 1A as priority path for half and 1B as priority path for remaining half (At NSC UVM)
This would ensure all the four external paths get used.
So i would like to to know how to this procedure online and how to use UVM here to configure the ports with respect to UVM.
Can any one suggect me how to proceed here.
