[ldoms-discuss] fun with iscsi

Hi,

You can virtualize a LUN and present it to a guest domain. It'll see it as if it were a local disk. At the moment, we ca not assign HBA's or virtualize them for guest domains. But you can definitely take your current SAN LUNs, virtualize them, and present them to the guest domain.

You can use iSCSI within a guest domain. I've tried this out and it works well. In my setup, I turned some ZFS volumes on my workstation into iSCSI devices and gave access for the primary domain. I was able to virtualize the iSCSI disks and use them to build a guest domain. I was also able to give the guest domain access to additional iSCSI disks and it was able to initialize and use them directly over the network.

Hi,

I have couple of questions, before i migrate my solaris environment to a LDOM environment. Currently i have 5 Solaris servers, each having Oracle and Clearcase applications and I use LUN for storage on each of the servers, so that i keep all backups and replication copies at the storage level. So my questions.

1. Can i discover LUNs inside a LDoms? If i create a LUN and map it to the server host, can i disover the LUN inside a LDOM using devfsadm and create a new fs on top of it?
2. Can i run iscsiadm inside the LDoms?
3. Can i assign a single FCP HBA to one LDom?

Thanks
Arun
