mostly I've seen this your Terminal's ability , if you are usign it
remotely and otherwise you have to define it accorindgly in your SHELL
if you are on the system itself,
Like I have enabled following on my Solaris 8 System as follows:

stty erase \^\?

in /etc/profile for the systemwide changes.

Hey all, I'm trying to emulate the F12 key while using a tip hardwire

a tip session on another Solaris host (sparc-based) which I use to
access the sytems.

I need to network boot the system, but instead of having to pull the
drives out (to force PXE boot), I would rather initiate the network
boot using the F12 key. In order to do so, I have to have a keyboard
attached to the systems.

For the V20z, it is esc-shift-2 via SP or serial console. It may vary
for other systems.

On 3 Feb 2006 13:21:58 -0800, Mike said something similar to:
: On my new sun V210, with the system up and running (Solaris 10) I pull
: the power plug, wait a few seconds, then plug it back in. It won't
: power back on until I hit the power switch or issue a poweron from the
: LOM prompt. How do I configure it to recover from a power failure
: automatically and remember that configuration?

From the ALOM:

setsc sc_powerstatememory true

or from the running system as root:
/usr/platform/`uname -i`/sbin/scadm set sc_powerstatememory true

: Secondly, how do I permanently disable the running of the (lengthy)
: diagnostic, every time it starts up. Again, I want the change to be
: permanent. Any help would be appreciated.

From OpenBOOT:

setenv diag-switch? false

or from the running system as root:
eeprom 'diag-switch?=false'

Note: the system boots from the device listed in the 'diag-device' variable
when diag-switch?=true and from the device listed in 'boot-device' when
diag-switch?=false. Make sure you're going to be booting from the correct
device after changing the value of 'diag-switch?'.

yes strange seems like suns first computer with default power off.
the blue sticker just say extended diag is run, nothing more.
the small psu fan close to the power connector tend to give up
in about a year or so. dont panic the system still runs fine
( more than months ), had no system stop, just higher fan revs.
install something to check /usr/platform/`uname -i`/sbin/prtdiag -v
so you can detect when the fan stops and change the psu.
Got 10% fan failure running ~166 v210's.

It appears my diag-switch is already set to false. However, my
diag-trigger is 'error-reset power-on-reset'. I'm going to try removing
the power-on-reset option and see what that does.

The SAN admin won't understand the veritas disk names - c2t0d7xs2. Is

Those aren't veritas names, it's from the OS.

The controllers are numbered sequentially as detected by the OS. You
can use the links in /dev/cfg to map from number to device.

The targets are mapped by the physical device driver. For instance a
SCSI device would have t equal to the SCSI target. Fiber drivers are
different. It depends on the specific driver. sometimes you can do
"hard binding" where you fix a particular WWN onto a target. "soft
binding" will just assign free targets to detected WWNs. The Sun
drivers will present a target equal to the WWN so it's pretty obvious.

If the disk is seen by the OS, you might be able to do an 'iostat -En'
and map the serial number from the device back to a physical or logical
device.

The OS (Solaris 10) doesn't seem to notice these disks: all the
"imported" SAN disks show up under the format command, but the ones
that are "not setup" do not.

Can you show the output of 'vxdisk list'? VxVM shouldn't be able to use
disks that you can't see in 'format'. Perhaps they're left over from
some previous configuration.

Also what is the output of 'vxdisk list c2t0d7xs2' (or whatever one of
the devices is...)?

You can also go through each volume which has been mounted XXX times and
mark this tape as readonly. So it won't be chosen again for backup, like:

mminfo -r volume -q '%used>0,!readonly,mounts>XXX' | \
while read tape; do
  nsrmm -o readonly $tape
done

mminfo scans each volume with data on it (%used>0) and isn't yet marked
readonly (!readonly) and has been mounted XXX times (mounts>XXX, replace XXX
with your desired number). For each such volume set the readonly flag
via nsrmm.

In another cycle you can then mark the tapes again as r/w. The mminfo/nsrmm
pair is a very powerful combination for automatic scripting, see the
manual pages:
mminfo(1M), nsrmm(1M)

Yes. Not which one, but any...
To match volumes that are nearline (in a jukebox).

mminfo -q 'near'

To report jukebox status

mminfo -r 'avail' ('n' means nearline or in a jukebox).
