TUR(8)TUR(8)NAMEtur - test unit ready
SYNOPSIStur [ -a b.t.l ] [ -l ]
DESCRIPTION
The tur program will send a TEST UNIT READY command to all SCSI devices
attached to the system.
-a b.t.l
Selects a specific ordinal SCSI address, where b is the logical
SCSI bus, t is the SCSI target, and l is the SCSI logical unit
number (LUN) on that target. See libscsi(8).
-l Performs a complete LUN search for all SCSI adapters in the sys‐
tem. 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 always shown, and the -l 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 -l option, all LUNS present on all target IDs for
all SCSI busses in the system will be checked for devices. This
can take a very long time and should therefore be used only 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.
