dump device is too small
请教个问题：
环境：AIX6.1 + VIOS2.2.1.4
有几个VIOclient的定时任务dumpcheck 会导致报The largest dump device is too small。
用sysdumpdev -e 会提示需要191T（有的分区会报-146G），而实际内存才有8G。
/VAR空间几乎没用。这会是什么问题？

Description
The largest dump device is too small.
Probable Causes
Neither dump device is large enough to accommodate a system dump at this time.
Recommended Actions
Increase the size of one or both dump devices.

是这个lv空间不够了/dev/lg_dumplv 跟/var空间没关系
sysdumpdev -e 显示出来的空间超过了你本来lv的空间 所以需要你extendlv收起

test/#sysdumpdev -e 确定空间期望大小
0453-041 Estimated dump size in bytes: 768396492
test/#extendlv 用这个命令再扩
Lg_dumplv是单独的跟/var使没使用没关系。
按这个步骤做，保证你errpt没报错。收起

dump是dump内存的数据的,或者说内存镜像
你内存只有8G，dump -e却显示是191133553315020，觉得是os bug吧
打下os补丁到一个稳定版本看看
不行就用一个在保的SN去问800收起

我觉得在保的话，直接打800解决了收起

人家真没算错，你看看sysdumpdev -e 的输出收起
