About Lx0 RAID on a stand-alone Profile XP
RAID chassis has one or two controllers, each of which have their own Ethernet
connection. This results in the following:
• PFR 700 RAID is one device on the control network, regardless of if it has one
or two controllers.
• Lx0 RAID with one controller is one device on the control network.
• Lx0 RAID with two controllers is two devices on the control network.
About Lx0 RAID on a stand-alone Profile XP
You can add Lx0 RAID storage devices to stand-alone Profile XP only as a
replacement. To fix a faulty RAID chassis, you remove the faulty chassis and replace
it with a new chassis. When you do this, you lose existing media.
Adding Lx0 RAID to a stand-alone Profile XP is supported as follows:
• Profile System Software must be at version 5.4.9 or higher.
• The Profile XP system must have the RTP-II board.
• The Fibre Channel connections must be 2 Gb/s.
• You must remove all RAID devices from the stand-alone Profile XP and replace
them with Lx0 RAID devices.
Take the following into consideration as you add Lx0 RAID to a stand-alone Profile
XP:
• Refer to the Installation Guide for your Profile XP model for detailed procedures
and related information as necessary. This document assumes you understand the
Profile XP system and that you are familiar with configuration procedures.
• You must bind Lx0 RAID disks as RAID 5, with 5 disks per LUN.
• A Lx0 RAID chassis has slots for 12 disks (slots 0 – 11), yet only 10 disks are
needed to fill out the two RAID 5 LUNs.
• Slots 0 – 4 must be used for one RAID 5 LUN. Slot 5 can be used for a Hot Spare
disk or you can put a blank in the slot. Slots 6 – 10 must be used for the other RAID
5 LUN. Slot 11 can be used for a Hot Spare disk or you can put a blank in the slot.
• A PFR 700 RAID has a single LAN card for Ethernet connection, while a Lx0
RAID chassis has one or two controllers, each of which have their own Ethernet
connection. This results in the following:
• PFR 700 RAID is configured as one device on the control network, regardless
of if it has one or two controllers.
• Lx0 RAID with one controller is configured as one device on the control
network.
• Lx0 RAID with two controllers is configured as two devices on the control
network.
