Hi Tru Gurus
About a week ago, I asked for Disaster Recovery Solutions for Tru64 5.1 and
LSM
Steve Smith has an interesting solution:
> What we do is make a non-LSM copy of root, usr and var on some local disks

the

bootable.
William H. Magill seperates OS and user data stricly. For DR he installs a
new OS
and restores the user data:

> Then lastly we deal with the real user data from the backup tapes.
> So, in short, the rebuild process takes on the order of 4-8 hours minimum.
Corinne Haesaerts sent me this link:

I didn't know this site, it can be very intresting for System
Administrators.
And also:

oh yes, this f... db, what is it good for? (Most of my systems have still
V4.0x)
Original question:
> With Tru64 V4.0x and LSM for the disaster Recovery we used to
> restore the root filesystem to a non-lsm disk; removed all
> lsm related in the root filesystem; restored /usr and
> reencapsulated LSM.
