recover removed /dev/dsk/c0t6d0 (root disk)

Stéphane Fromholtz — Thu, 04 Apr 2002 06:29:27 GMT

While removing other old files in /dev/dsk, I removed c0t6d0 which is the only PV in my vg00, and my root disk.

/dev/rdsk/c0t6d0 is still present, how can I recover this file without losing my data in vg00 ? Is pvcreate safe, or can I use mknod with options behind ?

Hi,

as 'root'

# cd /dev
# insf -e

This will fix the problem.

As mentioned insf will recreate youe dev-file.
DON'T run pvcreate as til will put a new LVMheader on the disk and you WILL loose your vg00.
