描述:P550两块盘hdisk0和hdisk1属rootvg且做了mirror,由于是实验机有时unmirror或重新mirror,一次做了这样的操
作,之前有同事做了实验后通过OP关了P550,过了几天,我重新开机,发现

原来两盘做了mirror,及加上之前的一系列操作造成破坏了rootvg的mirror从而产生STALE,且新生成的hdisk1的ID与原来
在rootvg中hdisk1的ID不一致,因此进行redefinevg与synclvodm操作,错误都在;
接着,尝试extendvg
# extendvg rootvg hdisk1
0516-322 extendvg: The Device Configuration Database is inconsistent.
Execute redefinevg to correct the database.
0516-792 extendvg: Unable to extend volume group.
显然,不行的
然后,从mirror上入手先,清除rootvg上的mirror
# unmirrorvg rootvg
0516-304 getlvodm: Unable to find device id 005787fd5f71a161 in the Device

0516-1246 rmlvcopy: If hd5 is the boot logical volume, please run 'chpv -c <diskname>'
as root user to clear the boot record and avoid a potential boot
off an old boot p_w_picpath that may reside on the disk from which this
logical volume is moved/removed.
0516-1804 chvg: The quorum change takes effect immediately.
0516-1144 unmirrorvg: rootvg successfully unmirrored, user should perform

有报错,但是提示起码说明,rootvg上的mirror的能清除;如下所示,且LV状态从stale变成syncd ,这是好事啊

总算,把这次由于人为的原因造成rootvg磁盘成员的故障的解决掉,现在就是要mirror回去了。

OK,问题到这总算完成。
总结,一,做任何操作前一定要对rootvg或其他vg做详细的检查,以避免人为造成故障;
二,对于本次的造成故障的解决归纳:# unmirrorvg rootvg,# reducevg rootvg hdisk#ID,
# synclvodm -P -v rootvg,# extendvg -f rootvg hdisk1,mirrorvg -S rootvg hdisk1
