Adding LUNs to VCS-controlled diskgroups online with disk-based fencing

Hi,

Can anyone describe a method to add LUNs to a VCS-controlled VxVM diskgroup when the disks in the diskgroup are protected using SCSI-3 fencing? We tried adding LUNs to a VCS-controlled diskgroup recently and got the following error message: " VCS ERROR V-16-10001-1036 (systemA) DiskGroup:dg1:monitor:No SCSI3 reservations found on diskgroup dg1". Is there a simple (or not so simple) way to add keys to new LUNs, without taking the diskgroup offline and online again? Our aim is to add storage without any outage.

Thanks, Alistair.
