Mike, make sure you do the rescan on the master host as well on all the slaves in the pool, especially if you are doing a "live" resize (i.e., not detaching the iSCSI SR from XenServer). Just issuing the rescan on the master will not propagate the info down to the slaves. We hit that problem while working on another [NetApp] product.
There is a current request into the Citrix XenServer team to provide a XAPI to do attached SR SAN resizes to avoid the "manual activity". I checked last night in Jira and didn't see any updates to that thread, so presumably the manual steps are still required--for now. Anyway, just a heads up. YMMV.

So, it sounds like on XenServer, you have to perform some manual activity for it to see the new size of the iSCSI target (and there is probably a similar requirement with ESX), but CloudStack will notice the size difference automatically (once the storage repository or datastore has been manually re-configured).

When the storage is brought out of maintenance mode, will it see the new size or is there something more that has to be done on the CS side? Thanks!

For example, let's say I'm using XenServer or ESX and I create a storage repository or datastore, respectively, for each hypervisor based on an iSCSI target. I then tie this into CloudStack as Primary Storage. If I increase the size of the iSCSI target (the SAN volume/LUN), does this increased size feed into the hypervisor and CloudStack?
