Solaris

I have been working on Windows and transitioning to Solaris 10 has been a steep learning curve.
My questions are:

1. In windows you can see Robotic arm under Medium Changer and Tape drives under Tape Drives in Device Manager if they are installed. How do you check these (Changer and tape drives) in Solaris 10?

2. In windows installing drivers is very easy for the medium changer and tape drives, how is it done in Solaris 10?

3. How do we check which tape drive is assigned to the path /dev/rmt/#cbn, if i dont know the path while using mt -f /dev/rmt/#cbn?

4. How do you install a Juke box, (starting from connecting the hardware to installing the drivers and checking the status)?

Thanks in advance.......

most of your questions are depended on the hardware you are using... so the best is to read the manufactures documentation...

to check the tape drives and changer device on Solaris 10 is using "cfgadm -al" command. or the detail command is "cfgadm -o show_FCP_dev -al". If you device connected already, then later you will see the line like this:

c4::500110a00094eafa,0 tape connected configured unknown
c4::500110a00094eafa,1 med-changer connected configured unknown

On solaris 10, to detect the new device is with "devfsadm" command. I think most of tape drives and tape library are supported by Solaris 10 and you don't need to install additional drives.

To check tape drives with the /dev/rmt/XX drives, you can check and compare base on its WWN and serial number. to show the S/N run the mt -f with 'config' option, exp: "mt -f /dev/rmt/0cb config"
to check the WWN on /dev/rmt/xx, try to run ls -ltr. Exp: "ls -ltr /dev/rmt/*cbn"

for last question, read jukebox installation guide..

Thanks Aziz,

I ran the cfgadm -al, it gives the following output


bash-3.00# cfgadm -al
Ap_Id Type Receptacle Occupant Condition
c2::273908001b80479e tape connected configured failed

i also ran show_FCP_dev -al

Ap_Id Type Receptacle Occupant Condition

c2::2100001b321aa150 unknown connected unconfigured unknown
c2::273908001b80479e med-changer connected configured unknown


If you notice, the Ap_id c2::273908001b80479e is showing as med-changer in the 2nd output and tape in the 1st output.

The library has 2 tape drives, i dont see them.

Hi Aziz,

I came across some more things.

i ran the ls -ltr /dev/rmt/*cbn command and it shows me 2 outputs

lrwxrwxrwx 1 root root 78 Jun 8 18:52 /dev/rmt/4cbn -> ../../devices/pci@7c0/pci@0/pci@8/SUNW,qlc@0/fp@0,0/st@w273908001b80479e,2:cbn
lrwxrwxrwx 1 root root 78 Jun 8 18:52 /dev/rmt/5cbn -> ../../devices/pci@7c0/pci@0/pci@8/SUNW,qlc@0/fp@0,0/st@w273908001b80479e,1:cbn

If you notice the WWN no. of both of them are similar, also cfgadm -o show_FCP_dev -al shows the medium changer with the same Ap_id.

I also checked the /etc/path_to_inst file and it shows me entries with the same WWN or the Ap_id.

I am confused. Please Help
