*VG名の変更 [#l041833e]
DASDをコピーしたクローン先のDASDをマウントするがVG名が競合するとマウントできない。そこで、VG名の変更を実施する。
作業はシングルユーザーモード(ランレベル1)にて行う。
# init 1
test01側のVG名を変更する
# vgrename test01vg test01tvg
# vgchange -u test01tvg
# pvchange -u /dev/dasda3
# pvchange -u /dev/dasdb1
# pvchange -u /dev/dasdc1
コピー先のtest02側のDASDを有効化するが、VG名はtest01用のためtest02用VG名の変更を行う。
DASDのonline
# chccwdev -e 5906
# chccwdev -e 5907
# chccwdev -e 5908
test02側のVG名を変更する。
# pvscan
# vgrename test01vg test02vg
# vgchange -u test02vg
# pvchange -u /dev/dasdd3
# pvchange -u /dev/dasde1
# pvchange -u /dev/dasdf1
VG名の変更が完了したらランレベルを3に移行する
# init 3
*test02用の設定 [#ic992686]
test02側の設定を行うためにtest01にファイルシステムをマウントする。
-test02側のPhysical volumeの確認
test01:~ # pvscan
