The following steps assume the user has rootvg contained on hdisk0 and is
attempting to mirror the rootvg to a new disk: hdisk1.
1. Extend rootvg to hdisk1 by executing the following:
2. Disable QUORUM, by executing the following:
3. Mirror the logical volumes that make up the AIX operating system by
executing the following:
If you have other paging devices, rootvg and non-rootvg, it is
recommended that you also mirror those logical volumes in addition to
hd6.
If hd5 consists of more than one logical partition, then, after mirroring hd5
you must verify that the mirrored copy of hd5 resides on contiguous
physical partitions. This can be verified with the following command:
If the mirrored hd5 partitions are not contiguous, you must delete the
mirror copy of hd5 (on hdisk1) and rerun the
mklvcopy
for hd5, using the
extendvg rootvg hdisk1
chvg -Qn rootvg
mklvcopy hd1 2 hdisk1 # /home file system
mklvcopy hd2 2 hdisk1 # /usr file system
mklvcopy hd3 2 hdisk1 # /tmp file system
mklvcopy hd4 2 hdisk1 # / (root) file system
mklvcopy hd5 2 hdisk1 # blv, boot logical volume
mklvcopy hd6 2 hdisk1 # paging space
