5#  Spin up the given SCSI disk(s).
6#
7#  SCSI disks (or disks that understand SCSI commands)
8#  are assumed. By default, the immediate bit is set so the
9#  command should return immediately. The disk however will
10#  take 10 seconds or more to spin up. The '-w' option
11#  causes each start to wait until the disk reports that it
12#  has started.
13#
14#  This script assumes the sg3_utils package is installed.
