frecover -x -i / -f /dev/rmt/1m leads to frecover(4305): not enough memory for allocate

[EU-Admins-UNIX]

Hi

Trying to recover a system at DR test.  O/S has ignited and when time comes to run the frecover, we get the following:

frecover(4305): not enough memory for allocate

Please see parameter settings below, as well as other outputs.

System has 64GB memory, running HP-UX 11.31 patched to March 2010.

Hi:

If you have killed any of the 'fbackup/frecover' sessions you may have left orphaned shared memory segments holding memory.  I'd reboot if that's the case.

Are you using a custom 'config' file with 'readerprocesses' set to a high value (the range is 2-6 with 2, the default).  If so, try reducing that value.  The file normally resides in '/var/adm/fbackupfiles'.

Regards!

Thanks James

We have rebooted, and still get the same issue.

there is no /var/adm/backupfiles file.

Hi:

Do you have patch PHCO_40460 installed?  It addresses the very error you have:

frecover(1M) fails with an error message like
	"frecover(4305): not enough memory for allocate"
	when fbackup(1M) was used
	1. with a blocksperrecord value greater than 9765
	2. in a locale where the date starts with digits,
	like "2008 Jun 26 02:29:39 Thu"

Regards!

Some things to look at:

1. What value do you have for the kernel parm maxdsiz?

2. Do you have patch PHCO_40460 installed - this seems to fix error conditions similar to what you describe

You have maxdsiz all the way at 4 Gb but frecover can only use 1 Gb.  (Unless you use chatr on your PA system.)

>you may have left orphaned shared memory segments holding memory.  I'd reboot if that's the case.

Any reason not to use ipcrm(1) instead of a reboot?

>1. What value do you have for the kernel parm maxdsiz?

The attached file showed 4 Gb.  With 172 Gb free.

Patch added, still facing the same issue!

The params are set OK, way over the min required.

For maxdsiz, since you don't know the minimum required, you can't really say that.  But your maxssiz is reasonable, 70 Mb.

I suppose you could run tusc on frecover and see where it goes wrong.

Or just use top to watch the memory use and see if it gets close to 1 Gb.
