AIX Dump Size 계산 및 LV 용량 증설 하기.

 

Dump Size 작아서 발생하는 메세지... Dump Size를 늘려 보자 

 

 

1. 로그 확인

root@svr:/ >errpt

IDENTIFIER TIMESTAMP  T C RESOURCE_NAME  DESCRIPTION
E87EF1BE   0710150019 P O dumpcheck      The largest dump device is too small.
E87EF1BE   0709150019 P O dumpcheck      The largest dump device is too small.

 

 

2. 덤프확인

root@svr:/ >sysdumpdev -l
primary              /dev/lg_dumplv
secondary            /dev/sysdumpnull
copy directory       /var/adm/ras
forced copy flag     TRUE
always allow dump    FALSE
dump compression     ON
type of dump         fw-assisted
full memory dump     disallow

 

3. 덤프사이즈 체크 

root@svr:/ >/usr/lib/ras/dumpcheck -p
The largest dump device is too small.
Largest dump device
         lg_dumplv
Largest dump device size in kb
         4194304
Current estimated dump size in kb
         4226703

 

4. LV용량 증설 

smitty extendlv 후 dumplv 증설  , 증설 후 /usr/lib/ras/dumpcheck -p 시 아무 메세지 없으면 '정상'

root@svr:/ >/usr/lib/ras/dumpcheck -p
