由于直接将存储划分的lun删除掉，忘记拆分vg与pv，现在进行删除vg和pv都报错。
信息如下：
db11#[/]lspv
hdisk8 00c40d950ffee695 backup_vg active
db11#[/]lsvg
backup_vg
smit删除报错：
Command: failed stdout: yes stderr: no
Before command completion, additional instructions may appear below.
0516-062 lqueryvg: Unable to read or write logical volume manager
record. PV may be permanently corrupted. Run diagnostics
0516-882 reducevg: Unable to reduce volume group.
reducevg也报错，
db11#[/]reducevg -d backup_vg hdisk8
0516-062 lqueryvg: Unable to read or write logical volume manager
record. PV may be permanently corrupted. Run diagnostics
0516-882 reducevg: Unable to reduce volume group.
errpt也一直报错：
