Added disk drives, but devices didn't get created

[Glenn Mitchell_4]

I added a HP SureStore E Disk System HVD10 which has 10 drives to a HP D370 10.20 system. When I powered up and ran ioscan -fnCdisk, I see the new hardware but not what device (/dev/dsk/c?t?d?) they are. The devices didn't get created. I'm used to seeing the devices being created automatically. Does anyone know why they wern't and the easiest way to?

Hi Glenn:

To create your device files, use 'mksf':

# mksf -C disk -I INSTANCE -v
# mksf -C disk -I INSTANCE -v -r

...where INSTANCE is the instance number from your ioscan. The '-r' option creates the raw device files you need. The '-v' specifies verbose messages.

Regards!

Hi,

Here is another post from you for the same question.

Glen,

Devices don't get created automatically.
You would need to run ?nsf command to
create the device entries.

Get the Hardware path of the device(s)
from the ioscan -nf output. Then, run

insf -e -H to create the devices.

The devices which you thought got
created automatically may have been done
by the device install scripts (whichever
device they are) or by a Reboot (insf runs
during boot process).

Hi Glenn:

If you want to do this from SAM, it's quite easy as well:

SAM->Disks & Filesystems -> Disk Devices -> Actions -> Diagnose Missing Disks.

It will essentially do the mksf command for you.

One possible cause for device files not being created is if there *used to be* hardware at the 'new' addresses. ioinit(1M) 'remembers' this and no new device files will be created. This is an intentional feature for temporary unavailable hardware, for example a card/device needs to be repaired and (of course) you do not want all device names to change as a result.

This can be fixed with "rmsf -k -H ...".
