Dump device error

2011年5月16日巡检主机时发现报错:

E87EF1BE 0515150011 P O dumpcheck The largest dump device is too small
解决方案:
1.查看当前dump device设备:
root:/>sysdumpdev -l
primary /dev/lg_dumplv
secondary /dev/sysdumpnull
copy directory /var/adm/ras
forced copy flag TRUE
always allow dump FALSE
dump compression OFF
2.查看lg_dumplv大小:
root:/>lslv lg_dumplv
LOGICAL VOLUME: lg_dumplv VOLUME GROUP: rootvg
LV IDENTIFIER: 000ceb7e00004c0000000103c5730303.10 PERMISSION: read/write
VG STATE: active/complete LV STATE: opened/syncd
TYPE: sysdump WRITE VERIFY: off
MAX LPs: 512 PP SIZE: 128 megabyte(s)
COPIES: 1 SCHED POLICY: parallel
LPs: 20 PPs: 18
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.查看lg_dumplv大小的估计值:
root:/>sysdumpdev -e
0453-041 Estimated dump size in bytes: 2465202176
4.查看lg_dumplv所在的vg容量是否够用
root:/>lsvg rootvg
VOLUME GROUP: rootvg VG IDENTIFIER: 000ceb7e00004c0000000103c5730303
VG STATE: active PP SIZE: 128 megabyte(s)
VG PERMISSION: read/write TOTAL PPs: 1092 (139776 megabytes)
MAX LVs: 256 FREE PPs: 439 (56192 megabytes)
LVs: 15 USED PPs: 653 (83584 megabytes)
OPEN LVs: 12 QUORUM: 1
TOTAL PVs: 2 VG DESCRIPTORS: 3
STALE PVs: 0 STALE PPs: 0
ACTIVE PVs: 2 AUTO ON: yes
MAX PPs per PV: 1016 MAX PVs: 32
LTG size: 128 kilobyte(s) AUTO SYNC: no
HOT SPARE: no BB POLICY: relocatable
5.扩容
root:/>extendlv lg_dumplv 2
6.使用dumpcheck查看是否有errpt信息
root:/>/usr/lib/ras/dumpcheck
root:/>errpt
成功!
