问题描述：
1、一个datavg，忘记varyoff datavg了，直接exportvg datavg了，然后lspv 发现盘都没了，然后lsdev -Cc disk显示：
lsdev -Cc disk
hdisk0 Available 10-60-00-0,0 Other SCSI Disk Drive
hdisk1 Available 10-88-00-6,0 Other SCSI Disk Drive
hdisk2 Available 10-88-00-6,1 Other SCSI Disk Drive
hdisk3 Defined 20-60-02 Other FC SCSI Disk Drive
hdisk4 Defined 20-60-02 Other FC SCSI Disk Drive
hdisk6 Defined 20-60-02 Other FC SCSI Disk Drive
hdisk7 Defined 20-60-02 Other FC SCSI Disk Drive
hdisk8 Defined 20-60-02 Other FC SCSI Disk Drive
hdisk9 Defined 20-60-02 Other FC SCSI Disk Drive
hdisk10 Defined 20-60-02 Other FC SCSI Disk Drive
hdisk11 Defined 20-60-02 Other FC SCSI Disk Drive
hdisk12 Defined 20-60-02 Other FC SCSI Disk Drive
hdisk13 Defined 20-60-02 Other FC SCSI Disk Drive
hdisk14 Defined 20-60-02 Other FC SCSI Disk Drive
hdisk15 Defined 20-60-02 Other FC SCSI Disk Drive
hdisk16 Defined 20-60-02 Other FC SCSI Disk Drive
hdisk17 Available 20-60-02 Other FC SCSI Disk Drive
hdisk18 Available 20-60-02 Other FC SCSI Disk Drive
hdisk19 Available 20-60-02 Other FC SCSI Disk Drive
hdisk20 Defined 20-60-02 Other FC SCSI Disk Drive
hdisk21 Defined 20-60-02 Other FC SCSI Disk Drive
hdisk22 Defined 20-60-02 Other FC SCSI Disk Drive
2、执行cfgmgr报：
cfgmgr
Method error (/usr/lib/methods/cfgecpa -l ppa1 ):
0514-043 Error getting or assigning a minor number.
3、把rmdev -hl hdisk5 删掉，然后chdev -l hdisk5 -a pv=yes 出现如下错误：
chdev -l hdisk5 -a pv=yes
chdev: 0514-519 The following device was not found in the customized
device configuration database:
hdisk5
现在没思路了，请指教该从那些方面下手，我的目的是把datavg找回来！谢谢！
