UNIX for Dummies Questions & Answers

Hi,

I have a server which is running out of space on the rootvg. When trying to find some spare space I discovered there are 2 sysdump logical volumes, each of 5GB, yet if I get an estimate of the dump size it's only 0.5 GB.

Code:

$ lsvg -l rootvg|grep sysdump
hd71                sysdump    20    20    1    open/syncd    N/A
hd72                sysdump    20    20    1    open/syncd    N/A

(PP Size = 256MB)

$ sysdumpdev -e
0453-041 Estimated dump size in bytes: 517577113

This is a huge waste of disk space so I want to know how to reduce the size of these sysdumps so I can recover the space.

Can anyone help?

Regards

Gareth

Make sure of what your setup is at the moment
sysdumpdev -l ( listing your setup )

I think you may find Primary go to one and Secondary go to the other

You can tes the Secondary to use your paging space

and free up the space that way

Also you can set the

sysdupdev -P -s /dev/hd6
sysdupdev -P -p /dev/sysdumpnull

then Chenge the size of the dump
hd71 or hd72 then set it back



Look at your rootvg for any filessystems you can take some space from

use chfs -a size=xxxxx /mount_point
where xxxxx is the new reduced size to use ( depending on your OS-level)
