You can hot-add storage enclosures that support hot-adding if the controllers support this as well, the MD1000s from Dell support this as do the LSI 1068 and 1078 based controllers. Just cable the new enclosure while it is powered off, then after it is cabled, power it on and after a minute rescan the controller with an 'update_drv -f mpt' for 1068s or 'update_drv -f mega_sas' for 1078s (after configuring luns through MegaCli). You can then add the new disks to an existing pool or create a new pool. If you are doing MPXIO over mpt driver, you may need to do a stmsboot -u to get the new multipath devices, but I don't think that is necessary any more, the 1078s do MPIO behind the scenes (with latest firmware). -Ross _______________________________________________ storage-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/storage-discuss
