is it best practice to exclude all subnets except the iscsi subnet?

The VDS/VSS control volume is for allowing VDS and VSS access to the group when using Auto Snapshot Manager Microsoft edition.  You create a access policy from the Group GUI (with v7.x of the Firmware you can create either a Group, Access or basic policy).  You do not need to map any of your hosts to the volume.

The Online help (you can launch this inside the Group GUI, using the "?") and the group administrator guide has all the information how to set it up.

Hi,

I've created an access policy and granted iqn names of the hosts. So far this part works fine as I can see vss control volume is being mapped to the hosts. However, ASM shows invalid/missing credential on VDS/VSS access. If I type anything as username and long password (12 characters) then pass the credential which I dont understand when and where ASM use these values?

thanks

I think I've found an answer for my question. Under the Group Configuration>iSCSI tab there is local chap account option which username and password can be set.

The following docs provide useful info on this topic.  Please let me know if I can provide additional information.

Refer to Section '4.3 Configuring EqualLogic PS Series Group Access settings' in the following doc:
