i didn't try that on a machine connected to a SAN yet (or, in fact, with
any SCSI HBA), but i think it only reports to you, the user, about the
SCSI targets (LUNs?) it sees - it does not make new SCSI disks appear on
the system.
Was this (making these SCSI devices appear on the system) part of the original question?
To quote the original question again:
The tool should do the following:
1) Find all HBAs in the host.
2) Query each HBA (should be HBA agnostic)
3) Query each device returned by HBA query, and extract the following: size,type,vendor
I am looking for preferably opensource or atleast free tool, I am
aware of some comercial tools that do this, i.e EMC's inq program.
