How do I know if there is a Jamaica connected to my L-Class?

[GBR]

I need to determine if there is a Jamaica connected to my L-Class. This is what I have:

Class I H/W Path Driver S/W State H/W Type Description
=====================================================================
disk 0 0/0/1/1.2.0 sdisk CLAIMED DEVICE IBM DMVS09D
/dev/dsk/c1t2d0 /dev/rdsk/c1t2d0

disk 6 0/3/0/0.3.0 sdisk CLAIMED DEVICE SEAGATE ST34573WC
/dev/dsk/c4t3d0 /dev/rdsk/c4t3d0

Any thoughts?

According to the "User's Guide", the disk array controllers are identified as C3586A in your ioscan output. You can check like this:

ioscan -f |grep C3586A

A jamaica (HASS) will just show up as a list of individual disks. This is because the HASS does not have any controllers - it's simply a means to connect up to 8 disks to a system in an external enclosure - much like an SC-10. The only way to tell is to walk over to the thing and look at it ... You'll know if it's a jamaica, it'll look like something from the smithsonian.

Friends the records of Jamaica are the following ones :
disk 8 0/3/0/0.1.0 sdisk CLAIMED DEVICE SEAGATE ST34572WC
/dev/dsk/c4t1d0 /dev/rdsk/c4t1d0
disk 5 0/3/0/0.2.0 sdisk CLAIMED DEVICE SEAGATE ST34573WC
/dev/dsk/c4t2d0 /dev/rdsk/c4t2d0
disk 6 0/3/0/0.3.0 sdisk CLAIMED DEVICE SEAGATE ST34573WC
/dev/dsk/c4t3d0 /dev/rdsk/c4t3d0

the 2 first ones of the list are internal

Calandrello,

How could you tell from my ioscan that the last 3 disks are part of the Jamaica?

There is absolutely no way to positively identify that the last 3 disks listed are indeed within a Jamaica enclousure. They could be the same Seagate drives enclosed in any other enclosure. A Jamaica is a JBOD (Just a Bunch Of Disks) and there is simply no way to say with certainty. You could have a 1 of those disks in one Jamaica enclosure and the other two disks in another non-HP enclosure and ioscan couldn't tell the difference. Now having said all this you can certainly see what is attached to your L-box. Hardware path 0/3/0 corresponds to slot 10 on an L-box and you should find the DIP switches on the back of the JBOD set to 1, 2, and 3 to match SCSI target id's 1, 2, and 3 of each of these disks.

I have a Jamaica box connected to a old K370 server. The ioscan description of its drives are "SEAGATE ST34573WC." Based on their descriptions, the disks at 0/3/0/0.[123].0 appear to be in a Jamaica box. But, like others said, this isn't definitive.

GBR
it observes that you have 2 internal records, 1 DVD looking at the Hardware path surplus only the records of Jamaica

Thanks all.

Clay, thanks for your elaborate answer.
