HPUX集群在线调整锁盘

1、停止双机

cmhaltcl -f

2、激活锁盘VG

vgchange -c n lockvg

vgchange -a y lockvg

3、扩容VG，添加新存储磁盘，删除旧存储磁盘

vgextend /dev/lockvg /dev/disk/disk01_lkvg
vgreduce /dev/lockvg /dev/disk/disk112

4、导出map文件

vgexport -v -p -s -m /tmp/hj/lockvg_20200426.map /dev/lockvg
vgexport -v -p -f /tmp/hj/lockvg_20200426.file /dev/lockvg


--备机上操作

5、删除lockvg

vgexport /dev/lockvg
mkdir /dev/lockvg
mknod /dev/lockvg/group c 64 0x0a0000

6、导入vg
vgimport -v -m /tmp/hj/lockvg_20200426.map -f /tmp/hj/lockvg_20200426.file /dev/lockvg

7、修改cluster.ascii文件，替换锁盘信息

8、检测MC/SG配置是否有无

cmcheckconf -C cluster.ascii -P /etc/cmcluster/odspkg1/odspkg1.conf -P /etc/cmcluster/odspkg2/odspkg2.conf



8、重新分发VG

vgchange -a y /dev/lockvg
cmapplyconf -v -C /etc/cmcluster/cluster.ascii -P /etc/cmcluster/odspkg1/odspkg1.conf -P /etc/cmcluster/odspkg2/odspkg2.conf
vgchange -a n /dev/lockvg

9、启动双机
cmruncl -v
