Configuring Drives
Creating a Hot Spare
You can designate an available drive as a hot spare. If a unit degrades and a hot spare
the size of the degraded disk (or larger) is available, the hot spare will dynamically
replace the failed drive in the unit without user intervention. When this occurs, an event
notification is generated and appears in the list of alarms in 3DM.
It’s a good idea to select a hot spare after you create a redundant unit. In order to replace
a failed drive, a hot spare must have the same or larger storage capacity than the drives it
is replacing.
To specify a hot spare after the system is booted:
1. In the Available Drives section of the Maintenance page, select the drive by
checking the box next to it.
2. Click
Create Unit
.
3. In the dialog box that appears, select the configuration type Spare .
4. Click OK . You will see the spare appear at the top of the page, under Unit
Maintenance.
Adding a Drive
If you have a hot-swap carrier, you can add a drive to your system and make it available
through 3DM without powering down the system.
To add a drive through 3DM when you have hot-swap carriers:
1. Connect the drive physically to the controller.
2. In 3DM, choose Management > Maintenance .
3. Click Rescan Controller .
The drive will appear in the list of available drives. You can now use it in a new RAID
configuration, or as a replacement drive in the event that another drive degrades.
4. If you want to use this drive as a spare, see “Creating a Hot Spare” above.
Removing a Drive
If you have a hot-swap carrier and want to physically remove a drive from your system
without powering it down, you must first remove it through the 3ware software.
