Unit Object Commands

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 67 and “/cx rescan

[noscan]” on page 50.

You may also need to resize the file system or add a new partition. For

instructions, consult the documentation for your operating system.

Example of splitting a mirror

//localhost> /c1/u3 migrate type=single

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.

Example of capacity expansion

//localhost> /c0/u3 migrate type=raid10 disk=10-11 stripe=16

Indicates that 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.

Example of migrate output

The following is an example of how migrating units will be displayed. In this

example, the report indicates that

/c0/u3 is a migrating unit with 39%

completion. The report also indicate that Source Unit

su0 is of type RAID-1

and Destination Unit

du0 is of type RAID-10.

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.

Warning: Make sure that no I/O is pending before splitting a mirror. If the RAID 1

is the boot device, you should boot from a different device before splitting the mirror.
