DDS type

Zeev Schultz — Tue, 25 Feb 2003 12:55:18 GMT

Hello all,
Is there any way to know what kind of DDS (1,2,3,4) drive I have via hp-ux commands only?
I tried diskinfo -v /dev/rmt/0m - it returns some unclear values like:
ANSI version (probably scsi-1,2,3?)
response format (no idea what is that)
and size (could be usefull,ie shows me 4gb for
a dds-2 drive).STM also does some information
show,but more on firmware etc,not dds type.

What dev-files you are using with
your tape-drive: #ls -l /dev/rmt

/dev/rmt/c2t0d0DDS2 for 8GB;
/dev/rmt/c2t0d0BEST for 40GB;
as to 4GB only read is supported.

Hi Zeev,

you can use
# ioscan -fnkC tape
tape 0 0/0/1/0.3.0 stape CLAIMED DEVICE HP C1537A

and do a search on google for C1537A --> returns DDS-3

Hope it helps,

Robert-Jan.

Hi Zeev,

do a
ioscan -fn I tape
(I is pipe) and you will see the desciption of your drive.
Infos about the drive you will get at
http://h20000.www2.hp.com/bizsupport/TechSupport/Product.jsp?prodTypeId=43563
or display it here at the forum.

Good point but /dev/rmt/DDSx (with x=1,2...) are created by
user in my opinion.For example,my ioscan shows
/dev/rmt/DDSn where n is no rewind.One of my customers used to create /dev/rmt/DDSx for compatibility issues with DDS-2,while he had DDS-4.

Thanks

Thanks Volkmar,looks promising.I hope ioscan
allways shows correct product numbers (ie C1533A) for tapes.

Hi Zeev,

C1533A is a DDS-2 (like I have) - 90m-tapes - 2GB native or 4GB
compressed.

And yes, it shows the right types, also of disks, CD-ROM, floppy (without 'pipe grep ..')

Nice day

ioscan -fnCtape will give you dds type.

Device Files you can create with different compressions like dds1.dds2 etc. You have backward compatibility.

dds2 tape can be read on dds3 drive but not a vice a versa.
