When hot-relocation occurs, subdisks are relocated to spare disks and/or available free space within the disk group. The new subdisk locations may not provide the same performance or data layout that existed before hot-relocation took place. You can move the relocated subdisks (after hot-relocation is complete) to improve performance.
You can also move the relocated subdisks of the spare disks to keep the spare disk space free for future hot-relocation needs. Another reason for moving subdisks is to recreate the configuration that existed before hot-relocation occurred.
To: root Subject: Volume Manager failures on host teal Attempting to relocate subdisk mydg02-03 from plex home-02. Dev_offset 0 length 1164 dm_name mydg02 da_name c0t5d0s2. The available plex home-01 will be used to recover the data.
This message has information about the subdisk before relocation and can be used to decide where to move the subdisk after relocation.
Here is an example message that shows the new location for the relocated subdisk:
To: root Subject: Attempting VxVM relocation on host teal Volume home Subdisk mydg02-03 relocated to mydg05-01, but not yet recovered.
Before you move any relocated subdisks, fix or replace the disk that failed.
Once this is done, you can move a relocated subdisk back to the original disk as described in the following sections.
