the the increasing of /var will be the selution .

Not exactly, increasing the dumpl LV lg_dumplv will be the solution, can be done with a simple extendlv... Check the second dump device (if any) as well...

Dear all

i have this error in my AIX and i can't increase the space for the lg_dumplv

is there any way to delete some files to have more space in lg_dumplv

This message can be annoying, since the dumps are compressed (assuming you set that - what is the output of sysdumpdev -l?), and the error shows an estimate, it's usually never close to what's actually needed.

If you have no space in the volume group to extend the LV, then either:

  • Add another disk to the volume group
  • Reduce other LV's in the VG, and add the space to the dump device LV
  • Move the dump device to another location where space is available (then, assuming it's in the same VG, you can remove the lg_dumplv, and use it to extend the new location)

Yeah that is what you need to do. Add a new disk from san and create the dump lv there. You can have pri and secondary as well if you add mirrored disks.
