make_recovery on non local tape drive

[Franky Leeuwerck_2]

Hi,

Only on the 1st of my 2 hp-ux systems there is a tape drive attached.

Can I make an Ignite make_recovery tape of system 2 using the tape drive on system 1 ?

Thanks in advance,
Franky

No.

If you have sufficient disc space you can do a make_net_recovery, but ignite cannot write to remote tape drives.

As Mark says, Ignite can not write to a remote tape drive. You can do a make_net_recovery and then dump that to tape. See Chapter 10 of the Ignite Administration Guide:

Hi,


This is my diskspace on /var:
/dev/vg00/lvol8 2097152 1668536 425360 80% /var
/dev/vg00/lvol10 4194304 17496 3915765 0% /var/adm/crash

Because I am not sure how much space I need I try to use the mounted filesystem /osbu.
But as you see, there are errors.

# hostname

# make_net_recovery -s myHost -a myHost:/osbu

1. What size is the OS disc on the system you want to backup?

2. How much free space do you have on the other system? Preferably not on an OS disc - I have dedicated discs for network backups.

So, this are my further questions :

1) How many diskspace do I need for a make_net_recovery ?

2) Can I run it from the same server with the archive on a mounted file system ?

Hi Mark,

The vg00 contains about 10 GB :
# bdf | grep vg00
/dev/vg00/lvol3 524288 221392 300552 42% /
/dev/vg00/lvol1 524288 128200 393040 25% /stand
/dev/vg00/lvol8 2097152 1668496 425400 80% /var
/dev/vg00/lvol10 4194304 17496 3915765 0% /var/adm/crash
/dev/vg00/lvol7 5242880 2636240 2586344 50% /usr
/dev/vg00/lvol4 1048576 696536 349352 67% /tmp
/dev/vg00/lvol6 5242880 3454872 1774088 66% /opt
/dev/vg00/lvol5 1048576 19560 1020984 2% /home
#

The mounted /osbu can handle 48 GB.

That should be enough to take an ignite backup of the other system. I would recommend the following:

1. Create a dedicated lvol for the backup. 10Gb will be enough if you only want to store a single backup of the other system; make it larger if you want two copies (e.g. at monthly intervals) or if there are other systems.

2. Export the new filesystem to the other system.

3. You will probably find the GUI version of ignite more user-friendly. It should be self-explanatory, but if you need any more help just ask.

Hi Mark,

The thing is, I don't have another system.
Can't I make the archive on a non vg00 file system that I can mount from a SAN ?

Doesn't your first post refer to two systems?

If you only have one, you will need to find a tape drive to attach to it. It cannot do a make_net_recovery to itself: you would be unable to access the backup if the OS disc went down. And the OS disc going down is precisely the time you would need the backup.
