then use CLI commands to 'remove' and 'rescan' the unit so that the
operating system can see the new capacity, and then remount the unit. For
details see "/cx/ux remove [noscan] [quiet]" on page 82 and "/cx rescan
[noscan]" on page 59.
You may also need to resize the file system or add a new partition. For
instructions, consult the documentation for your operating system.
Warning:
It is important that you allow migration to complete before adding drives
to the unit. Making physical changes to the unit during migration may cause the
migration process to stop, and can jeopardize the safety of your data.
Example of splitting a mirror
//localhost> /c1/u3 migrate type=single
Sending migration message to /c1/u3 ... Done.
In this case, the command indicates that u3 should be split into Single units. In
this case, u3 is a RAID 1 and the Migrate command splits u3 into u3 and ux,
each with a RAID type of Single.
Warning:
Make sure that no I/O is pending and that the unit is unmounted before
splitting a mirror. If the RAID 1 is the boot device, you should boot from a different
device before splitting the mirror.
Example of capacity expansion
//localhost> /c0/u3 migrate type=raid10 disk=10-11 stripe=16
Sending migration message to /c0/u3 ... Done.
In this case, the command indicates that the source unit is u3 and the
destination unit has a RAID type of raid10 and has added the disks 10 and 11
to the disks in the existing unit u3.
