VPD 0x83 info

[Ernest Siu]

What tool is available to find out the VPD page 83 information from a disk?

[Patrick Wallek]

Is 'diskinfo -v' what you are looking for?

# diskinfo -v c42t0d0

It doesn't seem to go far enough. This is from sg_inq from Linux and as far as I know the page 83 stuff is in byte 0x90 to 0x9f and that's way pass byte 90 from what I got in HPUX diskinfo -v.

[Torsten.]

What are you looking for? The serial number?
In this case you can use stm on this disk.

[Ernest Siu]

Not the serial number. I tried 'stm' with 'Tools'->'Information'->'Run' and it does give me the serial number. Actually that info is also available on diskinfo -v from byte (around byte 0x20 to 0x40 in sg_inq; the 4 byte-sequence of byte 0x34-0x37 of value 0x59 0x4f 0x54 0x41 also appears in diskinfo (47) (48) (49) (50)). I'm looking for the page 83 info in the sg_inq output byte 0x90 to 0x9f, which means in the diskinfo term, byte (113) to (128).

I'm looking for Vital Product Data on page 83 of the SCSI inquiry. From the sg_inq the 16 byte sequences I expect would look something like:
60 00 45 30 00 00 00 01 00 03 85 30 d3 cf c7 be

[Ernest Siu]

I found that the diskinfo command will genenrate additional inquiry bytes up to (138) on some device but on the device I'm interested in it only generates up to (90) which is not enough. I'm curious on why.
