Solution 1432156.1 : Sun SPARC(R) Enterprise M8000/M9000: 8mm DAT Drive & DVD is unavalable from domain(s)

Applies to:

Sun SPARC Enterprise M8000 Server - Version: Not Applicable and later   [Release: N/A and later ]
Sun SPARC Enterprise M9000-32 Server - Version: Not Applicable and later    [Release: N/A and later]
Sun SPARC Enterprise M9000-64 Server - Version: Not Applicable and later    [Release: N/A and later]
Information in this document applies to any platform.

Symptoms

The 8mm DAT drive nor DVD cannot be accessed in the M8000 domain(s).
The links to the devices under /dev/rmt and /dev/rdsk are not present.
The cfgadm -a command does not shows them.

Cause

Checking the status from the XSCF using the cfgdevice command shows:

XSCF> cfgdevice -l
Current connection for DVD/DAT:
Expander status
Port No. IOU/SAS-status SAS-status
-----------------------------------
0-0 disable down disable down
1-0 disable down disable down

note the "disable" status.

Solution

On the Sun SPARC Enterprise M8000 and Sun SPARC Enterprise M9000-32 since there is only one DVD/CDROM as well as only one DAT in the system.

Run the following from the XSCF to connect the DAT & DVD to the needed port based on the domain(s) configuration.

xscf> cfgdevice -q -y -c attach -p 0-0

Confirm that this has been attached by running

xscf> cfgdevice -l

This should now look like

Current connection for DVD/DAT:
Expander status
Port No. IOU/SAS-status SAS-status
-----------------------------------
0-0 enable up enable up
1-0 disable down disable down

Now check Solaris to see if these are available.

It's recommend to run the devfsadm command with the -nv flags to confirm what would be changed before making any changes.

# devfsadm -nv

(this will then list any changes that would be made running the devfsadm command without making any changes)

If happy with the changes that would be made then run the command with out the -n switch.

# devfsadm -v

The DAT drive and the DVD drive should now be available.

The cfgadm -a command will show them:

<...snip...>

c0::dsk/c0t4d0 CD-ROM connected configured unknown
c0::rmt/0 tape connected configured unknown

<...snip...>

Alternatively you can use the cfgadm command to configure the devices:

# cfgadm -c configure c0::dsk/c0t4d0
# cfgadm -c configure c0::rmt/0
