One of the AIX system faults-- deleting VG faults

System environment:

Operating system: AIX5300-08

Cause of failure:

Two paging spaces, lv_ps1 and paging01, are established on the datavg volume group. Without deleting the paging space, the datavg volume group is deleted first, and then the datavg volume group is re-established. When viewing the paging space, an error is reported.

5. Re-import and export VG

[root@/usr/lib/bootaix211] # redefinevg

Usage: redefinevg {- d PVname |-I VGid} [- V MajorNumber] VGname

[root@/usr/lib/bootaix211] # redefinevg-d hdisk1 datavg

[root@/usr/lib/bootaix211] # varyoffvg datavg

[root@/usr/lib/bootaix211] # exportvg datavg

[root@/usr/lib/bootaix211] # importvg

0516-604 importvg: Physical volume name not entered.

Usage: importvg [- V MajorNumber] [- y VGname] [- f] [- c] [- x]] | [- L VGname]]

[- n] [- F] [- R] PVname

Imports the definition of a volume group.

Export vg and then re-import it into the ODM library to resolve the problem

[root@/usr/lib/bootaix211] # importvg-y datavg hdisk1

Datavg

[root@/usr/lib/bootaix211] # varyonvg datavg

[root@/usr/lib/bootaix211] # synclvodm-v datavg

Synclvodm: Physical volume data updated.

Synclvodm: Logical volume lv_dsk1 updated.

Synclvodm: Logical volume loglv00 updated.

Synclvodm: Logical volume loglv01 updated.

Synclvodm: Logical volume fslv00 updated.
