I have 2 disks on separate SCSI busses that are striped to form a single vinum volume. They are recognized as da0 and da1 I want to add 1 more disk to each SCSI buss and create another striped vinum volume, but keep the initial vinum volume intact. The issue ... When the 2 disks are added to SCSI busses the first 2 disks in the initial volume are not recognized by the system in the same way. For instance ... disk SCSI buss ORIGINAL CONFIG PLANNED CONFIG disk1 1 da0 da0 disk2 2 da1 da2 disk3 1 da1 disk4 2 da3 The original vinum volume is configured on da0 da1 Under the planned config the original vinum volume will now be on da0 da2. While I could wire down the devices in kernel config .. Also I want to stripe to disks on separate busses so moving the secound disk onto the same bus as disk1 is not a good option I am still wondering if vinum will be able to build volumes correctly based only on the information stored in the per disk configuration even if the system sees them differntly. thanx - steve To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
