AIX 5.2 and DS4300 Storage

Hello,

We're setting up a solution for a group of customers with 2 p520 servers and 1 DS4300 unit with 9 disks (at this stage). The meaning is to create two arrays on the DS4300. Both servers will be connected to the DS4300 unit and to both controllers (e.g. Controller 1 connected to server 1 and 2 and Controller 2 connected to server 1 and 2 for redundancy) through fiber optics. My question is now: First. what do I set up as configuration on both servers under AIX 5.2 so that server 1 connects/only sees array 1 and server 2 connects/only sees array 2. Second. Can this configuration be changed in an easy way in case one of the servers is unavailable?

Any remarks/advice is greatly appreciated.

Kind regards,

Eric Van Steenbergen

NAME
icp -- ICP-Vortex and Intel Storage RAID driver SYNOPSIS
icp* at pci? dev ? function ? ld* at icp? unit ? icpsp* at icp? unit ? scsibus* at icpsp? DESCRIPTION
The icp driver provides support for the newer (post 1997) ICP-Vortex GDT and Intel Storage RAID controllers. The ld driver provides access to logical devices (disk arrays) presented by the controller. The icpsp driver provides direct access to other SCSI devices attached to the controller, such as tape or CD-ROM drives. DIAGNOSTICS
pci_mem_find: expected mem type 00000000, found 00000002 This message may be displayed during autoconfiguration if the controller's memory is mapped below 1MB in physical address space. This can be disabled either through changing a setting in the controller's BIOS utility, or changing the position of a jumper on the board. See your controller's documentation for more information. SEE ALSO
intro(4), ld(4), scsi(4) HISTORY
The icp driver first appeared in NetBSD 1.6, and was based on the FreeBSD and OpenBSD drivers of the same name. BUGS
ISA & EISA front-ends and a management interface are needed. Older PCI boards are not yet supported. BSD
