growisofs - error unable to umount /dev/rdsk/c26t2d0: No such file or directory

[Schimidt]

Hi,

When I ran /opt/ignite/data/scripts/examples/make_opticaldisc_recovery script (Ignite-UX-11-23 C.7.3.148) I notice an error in the step 6:

=== Step 6: Write image file to tape/CD/DVD media ===
+ /opt/ignite/lbin/growisofs -Z /dev/rdsk/c26t1d0=/var/opt/ignite/recovery/archives/drp02/image.iso

+ Error 83 /opt/ignite/lbin/growisofs failed.
/opt/ignite/data/scripts/examples/make_media_install: ERROR: /opt/ignite/lbin/growisofs failed.

It's possible simulate the error if I change instance number. e.g.: I change ext_bus from 1 to 26.

So, I can reproduce the error:

[root#] /opt/ignite/lbin/growisofs -Z /dev/rdsk/c26t2d0=/var/tmp/B.11.23.iso
:-( unable to open("/dev/rscsi/c1at2l0",O_RDONLY): No such file or directory :-! consider 'mknod /dev/rscsi/c1at2l0 c 203 0x1a2002; chmod 0600 /dev/rscsi/c1at2l0'

I follow the sugestion:

[root#] mknod /dev/rscsi/c1at2l0 c 203 0x1a2002; chmod 0600 /dev/rscsi/c1at2l0

But I have the error as follow:

Executing 'builtin_dd if=/var/tmp/B.11.23.iso of=/dev/rscsi/c1at2l0 obs=32k seek=0'

I tried this but I receive the same error:

[root#] mknod /dev/rscsi/c26t2l0 c 203 0x1a2002; chmod 0600 /dev/rscsi/c26t2l0

[root#] /opt/ignite/lbin/growisofs -Z /dev/rdsk/c26t2d0=/var/tmp/B.11.23.iso

:-( unable to umount /dev/rdsk/c26t2d0: No such file or directory

I think there are a problem using growisofs with controller instance number greater than 9.

Anybody have idea how to solve this?

I'd appreciate any help

This is a bug in growisofs.c code. The string "dev/dsk/c%xt%xd%x" %x is used however HP-UX uses decimal numbers in the device files not hex numbers. The I informed the hex number in the script /opt/ignite/data/scripts/examples/make_opticaldisc_recovery after create a link and solved the problem
