Re: [zfs-discuss] Modify stmf_sbd_lu properties
You can try to workaround - no idea if this would really work - 0) Disable stmf and iscsi/* services 1) Create your volume's clone 2) Rename the original live volume dataset to some other name 3) Rename the clone to original dataset's name 4) Promote the clone - now for the system it SHOULD seem like this clone was always here with this original naming, and your current newer dataset is a cloned deviation. Hopefully this will fool STMF into using this data instead of new data, with existing GUID... 5) Enable stmf and iscsi/* services *) Tell us if it works ;) HTH, //Jim -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] Modify stmf_sbd_lu properties
I can't actually disable the STMF framework to do this but I can try renaming things and dumping the properties from one device to another and see if it works- it might actually do it. I will let you know. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Re: [zfs-discuss] Modify stmf_sbd_lu properties
It turns out this was actually as simple as: stmfadm create-lu -p guid=XXX.. I kept looking at modify-lu to change this and never thought to check the create-lu options. Thanks to Evaldas for the suggestion. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] Modify stmf_sbd_lu properties
Don, Is it possible to modify the GUID associated with a ZFS volume imported into STMF? To clarify- I have a ZFS volume I have imported into STMF and export via iscsi. I have a number of snapshots of this volume. I need to temporarily go back to an older snapshot without removing all the more recent ones. I can delete the current sbd LU, clone the snapshot I want to test, and then bring that back in to sbd. The problem is that you need to use sbdadm create-lu and that creates a new GUID. (sbdadm import-lu on a clone will give you a metafile error). Take a look at the command set associated with stmfadm, and you should see that it has taken on all sbdadm options, and more. I believe you are looking for the functionality associated with stmfadm offline-lu, ... online-lu. - Jim Is it possible to change the GUID of the newly imported volume to match the old volume (even if that means changing the guid of the old volume first)? I had hoped this could be done by dumping the stmf_sdb_lu property from zfs and setting the clones property to this value- but that does not seem to work. Changing the guid is not an option for these tests. Any ieas? -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
