backup to file using fbackup or vxdump command

[Shashi Bhargava]

hi all,

i want to take a backup of my hp-ux system but i dont have any backup device. so i assigned a vdisk from my EVA 5000 to my hp-ux host and created one vg and lv and mouted it. when i try to take a backup of my hp-ux filesytem to a file(which is in the newly created lv). i am getting the following write error. What might be the problem. please help me to resolve this. i have tried with both vxdump and fbackup both are giving the same error message as below.

It looks like the volume is not working. Can you simply touch a file like:

touch /bkp_sr6/bkp1/data1.dump

If that fails, look at your syslog to see if there are error messages.

Peace be with thee.

It simply means your destination filesystem is not capable of storing LARGEFILES -- which still mean files greater than 2GB.

Did you create your backup/destination filesystem with the largefiles option?

If you need large file support you should be able to do:

fsadm -o largefiles /
