Configuring Disk Mirroring
Introduction to Disk Mirroring (RAID Level 1)
The Nokia disk mirroring feature protects against downtime in the event of a
hard disk drive failure in your appliance (for platforms that support the
feature). You must have a second hard disk drive installed on your appliance.
Disk mirroring gives you the ability to configure a mirror set comprised of a
source hard disk drive and a mirror hard disk drive using Voyager. The hard
disk drive in which you have installed IPSO is your source hard disk drive.
Once you have configured a mirror set, and the hard disk drives are
synchronized (source hard disk drive is fully copied to the mirror hard disk
drive), all new data written to your source hard disk drive is also written to
your mirror hard disk drive. If your source hard disk drive fails, your mirror
hard disk drive will automatically replace your source hard disk drive without
interrupting service on your appliance.
The source and mirror hard disk drives can be "warm swapped" on appliances
other than IP500 series appliances, which means you can replace a failed hard
disk drive without shutting down your appliance.
In addition to your being able to configure a mirror set, you can monitor the
status of a mirror set, synchronization time and system log entries.
Note

Getting Started Guide and Release Notes

creating a mirror set when you install IPSO.
