Hard-Disk Drives; Using Raid-1 - Nokia Check Point IP2450 Installation Manual

Hard-Disk Drives

The Check Point disk-based IP2450 appliance supports up to two hard-disk drives. The
hard-disk drives support hot swapping (when you use the hot swap button on the drive front
panel), and an optional RAID-1 feature, which is described in the following section.

Using RAID-1

The IP2450 contains a hardware RAID-1 feature that provides fault tolerance by allowing the
IP2450 appliance to continue working in the event of a disk failure.
When you use RAID-1 with your disk-based IP2450 with two hard-disk drives, the two drives
appear as one volume, which is named sd0.
Note
If your IP2450 contains two hard-disk drives when you receive it, the RAID-1 feature is
already enabled.
Note
If you add a second disk drive to implement RAID-1 be sure that your secondary drive is the
same capacity or larger than your primary drive.
If the two drives are completely synchronized, you can remove either drive after first pressing
the hot swap button and waiting until the Hot Swap Ready LED illuminates solid blue.
The RAID-1 volume consists of a master (or source) hard-disk drive (which holds the active
copy of the operating system) and a slave (or mirror) hard-disk drive. The slave hard-disk drive
contains a copy of all of the files on the master hard-disk drive, and if the master hard-disk drive
fails, the slave hard-disk drive immediately takes over. The IP2450 appliance continues to
operate normally, and the switchover to the slave drive should be transparent to your data
connections.
You can use Check Point Network Voyager or the command-line interface (CLI) to view RAID-
1 volume and synchronization status, current volume configuration, and the primary volume
designation.
You can, if necessary, configure a RAID volume with the Check Point IPSO boot manager. The
following actions are available to you under the boot manager raid command:
disable
enable
create
delete
activate
deactivate
