Problem with create LUN on disk Array

Massimo Travaglini — Thu, 27 Jan 2000 08:07:14 GMT

After created a LUN on a Disk Array and after created a phisical volume I'll
try to create a volume group but the system (HP-UX 10.20 on K570) doesn't have
the block device created, It has only the character device. You know about a
particular patch?

Thanks

Are you creating the VG through sam, or from the command line? If commands,
what syntax exactly are you using?

Are you talking about a block device for the disk itself, or the lvols? If for
the disk, that should be created when the system recognizes the disk, but can
be manually created with the insf command.

I used the command line, and I don't have the /dev/dsk/xxxxxx file, it's very
strange because the disk array procedure creates the /dev/rdsk/xxxxxx
correctly.

Thanks

Hi,

to create block device you can run:

1- insf -e. This command recreates all devices for your system

2- mksf -H harwdware_path and mksf -r -H hardwarepath. this other cretate both
block and character devices

or 3- mknod file b major minor and mknod c file major minor.

See man pages insf, mksf and mknod(1M)

Regards.
