I am trying to configure dump devices on my AIX server. Running 7100-03-04-1441. My dump device needs to be about 2GB in size. My PP Size is 1024MB, so I create the device with 2 PPs. When I run lslv on the dump device, it shows the 2 PPs, and a PP Size of 1024 megabytes. However, a dumpcheck -p shows that my dump device is only 256MB in size. dumpcheck seems to think my PP Size is only 128MB. Here you can see the output of lslv dump2lv showing the PP Size and PPs:
And here you can see dumpcheck showing the size being only 262144 kb:
My rootvg does show that the size used is indeed 2GB. So where is this extra space going, and why is dumpcheck not reporting all the size for my dump device?
Thanks in advance!
Code:

MAX LPs: 512 PP SIZE: 1024 megabyte(s)
COPIES: 1 SCHED POLICY: parallel
LPs: 2 PPs: 2
STALE PPs: 0 BB POLICY: non-relocatable
INTER-POLICY: minimum RELOCATABLE: yes
INTRA-POLICY: middle UPPER BOUND: 8
MOUNT POINT: N/A LABEL: None
MIRROR WRITE CONSISTENCY: on/ACTIVE
EACH LP COPY ON A SEPARATE PV ?: yes
Serialize IO ?: NO
INFINITE RETRY: no PREFERRED READ: 0And here you can see dumpcheck showing the size being only 262144 kb:
Code:
# /usr/lib/ras/dumpcheck -p
