Dear all

First of all, my English not so good.

We have p52a (production server) and p52a (test server). Tape drives are VXA2.

When both servers were AIX 5.3, mksysb on production server and restoring to test server was OK.

The production server was AIX 5.3 and recently upgraded to AIX 6.1 TL06 sp05 by migration install.

when I did mksysb on production server and then restored to test server, the following message appeared and got stuck:

"Please mount volume 2 on /dev/rmt0.1"

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Of course only one tape media was used and successful when I did mksysb. There was no error log.

I tried different tape medias and changing tape device "block size" also but results were same.

Moreover, I tried mkdvd backup on production server and restored it to test server, but it also didn't work.

When I tried lsmksysb, it shows the content of os backup for a while, but got stuck at following:

1828485 ./var/adm/messages.1.gz
           0 ./var/adm/ml
         102 ./var/adm/ml/rc.ml.log
         102 ./var/adm/ml/rc.ml.log.previous
           0 ./var/adm/nim
Please mount volume 2 on /dev/rmt0.1
... and press Enter to continue Out of memory, malloc() failed.
    23288448 ./var/adm/pacct

So, I assume that os backup itself has problem.

I installed AIX 6.1 (new & completed install) and mksysb on test server, then restored it to test server itself was OK.

Please find an attached file for your reference.

Actually, I did mksysb and restoring over 10 years but didn't see this kind of problem.

Anyone can help me?

Thanks in advance!

What is the size of your mksysb file? I have seen an issue when mksysbs went over 2GB in size. Your /etc/security/limits file contains a hard file size limit by default, even for root, of 2 GB. This means the mksysb create process will initially appear to go well, but the file will be truncated to 2 GB. Which means you now have an incomplete mksysb.

Change the /etc/security/limits file to get rid of this limit and you're done. If you do mksysbs over NFS (like NIM does), then do this both on the NIM server and on any clients.
