replication set is not displayed with the correct size after lun expansion

hello,

i recently expanded a lun from VNX that was replication set for one of the Consistency Groups in RPA.

i used the replication set wizard to edit the replication set. when i finished the operation, i noticed that in the replication set tab of the consistency group the size of my replication set is not changed. although when i double click on the replication set names i can see the correct size in the new window that opens.

but im not sure if this is a correct behavior after a lun expansion.

does anybody has an idea if this is a known behavior?

thank you

I think the issue here is that this is only supported with VNX OE code 32.

Log on as admin at the CLI and run the rescan_san command. Then check the size of the volumes in get_san_volumes. You can also run a SAN Diagnostics check using boxmgmt and then view the target LUNs.

This sounds like a bug whereby RP is faking the expanded LUN to it's original size at the first view. Can you also confirm the RP and VNX OE code versions.

i tried the rescan by both admin and boxmgmt but it still shows the old size when i execute get_san_volumes.

the RPA version is 3.5.SP2 and VNX version 05.31
