I'm trying to swap out a failed IDE drive on a 3Ware card. I went into tw_cli and executed "maint remove c1 p1" and it shows the drive offline. The disk is in what appears to be a hot-swap connection similar to SCA. Do I need to do the line below to remove it since the 3ware card registers the drive offline? root@legato-disk4.acs:~# tw_cli info c1 p1 Controller 1, Port 1 ---------------------- Status: OFFLINE JBOD Model: Maxtor 4G160J8 Size: 163.92 GB (320173056 blocks) Serial #: G805DE1E FW: GAK819K0 Unit: 1 /proc/scsi/scsi does still show the device: Host: scsi1 Channel: 00 Id: 01 Lun: 00 Vendor: 3ware Model: 3w-xxxx Rev: 1.0=20 Type: Direct-Access ANSI SCSI revision: ffffffff and the echo, remove below doesn't remove it. It does happily though work on some other systems with SCA interfaces. Thanks, Robert Thus spake Douglas Gilbert (dgilbert@interlog.com): > Robert L.
