relem - read element status
program will send a READ ELEMENT STATUS command to all changers, or
option) to the named device.
- -a b.t.l
Selects a specific ordinal SCSI address, where
is the logical SCSI bus,
is the SCSI target,
is the SCSI logical unit number (LUN) on that target. See
generates full output (somewhat verbose).
generates very verbose output.
causes volume tags, if present, to be printed.
causes the returned element status data to be dumped as hexadecimal codes
rather than interpreted.
Performs a complete LUN search for all SCSI adapters in the system when
performing Autodetection. This argument is accepted on all systems, but does not
have any effect on HP-UX systems. Due to the method used to scan for available
devices on HP-UX systems, all accessible devices are shown, and the
option has no additional effect. On all other systems, checking starts
at LUN 0 for SCSI devices. The first empty LUN found will end the
search for a given target ID. With the
option, LUNS on all target IDs for all SCSI busses in the
system are checked for jukeboxes. This can take a
very long time
and should only be used when necessary. For example, a Fibre
Channel adapter can support 126 target IDs, each of which may have 80 or
more LUNs. Checking all LUNs on this single adapter may take over 10 minutes.
- -m 0
all element status data is fetched in one call
- -m 1
element status data is fetched per element type (e.g., all drive
elements are read at once, then all slot elements, etc.)
- -m 2
element data is fetched per element (which is the default method)
The SCSI specification allows each of the previous methods of fetching element data.
some changers have defects with respect to fetching element data.
For example, one changer may be
accurate when reporting all elements of a particular type
(using method -m 1),
but return only zeros if asked for all elements at once
(using method -m 2).
is used to read a range of addresses, where
is the starting decimal address (in the particular changer's numbering scheme)
of the element to start from, and
is the number of elements of status to read. Use
to get the particular addresses used by your changer.
