[ANNOUNCE] lsscsi-0.26 released

lsscsi currently can provide some transport related
identifiers when the --transport (-t) option is used. This
will probably be a target port identifier rather than a LU
name (a.k.a. the WWN). Fetching the LU name has proven
elusive. The most direct way would be to issue an INQUIRY
to get the device identification VPD page but that would
require root permissions. A feature of lsscsi is that it
does not need root permissions (or related tricks).


This version adds a --wwn (-w) option which searches the udev
provided /dev/disk/by-id/wwn-* symlinks. This will find
WWNs (LU names) for disks if udev can find them.


There are two SATA disks in the example below: /dev/sda and
/dev/sdd . /dev/sda is older and has no WWN plus it is
directly connected to a SATA controller on the motherboard.
/dev/sdd has a WNN and is connected via a SAS expander.
