mksf boot disk

[Michael Steele_2]

Hey

Trying to correct a problem w/ rmsf -a /dev/dsk/c0t2d0. Which is the alternate boot disk. (* new guy *).

Tried mksf -C disk -H path -I 1

...get "...mksf: Couldn't find driver matching arguments..."

Any ideas besides rebooting?

[Patrick Wallek]

Use insf.

# insf -H

[Michael Steele_2]

WARNINGS
insf should only be run in single-user mode.

[Patrick Wallek]

I have run insf from multi-user mode plenty of times without any problems.

If the disk isn't functional then running insf for that particular HW path should not pose a problem.

[Michael Steele_2]

didn't work.

also tried insf -e before posting.

is this the correct syntax for mksf?

mksf -C sdisk -H 1/0/11/1/0.2.0 -I 1, given this old ioscan?

disk 1 1/0/11/1/0.2.0 sdisk CLAIMED DEVICE HP 73.4GST373207L

Hiya,

That's in the manpage, and kind of worrying indeed.

However, we use insf all the time, when adding SAN LUNs and when re-creating 'accidentally removed' special files.

# insf -C disk -e # should do the job

I can only say I've never triggered disasters using that one. To the contrary, it has saved our hineys a few times when /dev was emptied by an overconfident script.

No guarantees, though, seeing the manpage ;-)

Cheers,
Wout

>>didn't work.

What did it do or not do? I assume you /dev/dsk and /dev/rdsk files are still not there?

>>also tried insf -e before posting.

That could've been helpful.

>>Any ideas besides rebooting?

A reboot would just run insf.

What are you seeing now if you do an 'ioscan -fnC disk'?

Wouter:

So, already ran # insf -e, but your are recommending

insf -c disk -e 1/0/11/1/0.2.0 ??

[Michael Steele_2]

root@asap11[/usr/conf/master.d]:insf -C disk -e
insf: Installing special files for sdisk instance 0 address 1/0/11/1/0.0.0

[Patrick Wallek]

It looks to me like the system is not seeing the disk at all.

Since ioscan isn't seeing it, insf will not be able to do anything.

If this is a hot-pluggable / hot-swappable disk, I would remove it, wait a minute or 2 to let the disk spin down, then insert it into the slot again. Wait another minute or so to let the disk spin up and be recognized on the bus, then try another ioscan.

If it still doesn't show up, try another disk as this one may be hosed.

[Wouter Jagers]

New guy didn't take the disk home, by any chance ? ;-)

Myes, at this point I'd run down to the computer room for a physical inspection, too..

[Michael Steele_2]

Well, this is interesting.

Come in this morning and I can see the device in ioscan.

Run an 'insf -e' and the device file is created automagcally!
