1) Verificando o status do sysdump
# 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
2) Verificando o tamanho estimado para o dump
# sysdumpdev -e 0453-041 Estimated dump size in bytes: 1016279859
3) Verificando o tamanho da Área de DUMP
3.1) Encontrando o lv de dump
# lsvg -l rootvg | grep sysdump lg_dumplv
sysdump 96 96 1 open/syncd N/A
3.2) Verificando o tamanho dos PPs
# lslv lg_dumplv LOGICAL VOLUME: lg_dumplv VOLUME
GROUP: rootvg LV IDENTIFIER: 000c6a8d00004c000000011533b4b782.10
PERMISSION: read/write VG STATE: active/complete LV
STATE: opened/syncd TYPE: sysdump
WRITE VERIFY: off MAX LPs: 512 PP
SIZE: 32 megabyte(s) COPIES: 1
SCHED POLICY: parallel LPs: 96
PPs: 96 STALE PPs: 0 BB
POLICY: relocatable INTER-POLICY: minimum
RELOCATABLE: yes INTRA-POLICY: middle UPPER
BOUND: 32 MOUNT POINT: N/A LABEL:
None MIRROR WRITE CONSISTENCY: on/ACTIVE EACH LP COPY ON A SEPARATE PV
?: yes Serialize IO ?: NO
3.3) Calculando o tamanho da área em Mb
# echo 96*32 | bc 3072
4) Se quiser gerar um dump basta executar o comando abaixo *** ISSO VAI REINICIAR O SERVIDOR ***
# sysdumpstart -p
5) Gerando o SNAP com o DUMP
# snap -r # snap -gfktLDc
Ele vai gerar o arquivo:
/tmp/ibmsupt/snap.pax.Z
