MPIO RDAC IBM SAN STORAGE DS4700 ?

Hello,

I have AIX 6.1 with TL 4 and it is connected to IBM SAN STORAGE DS4700

After assigning some disks from SAN to AIX, I can see the disks in my AIX as

hdisk2 Available 05-00-02 MPIO Other DS4K Array Disk
hdisk3 Available 05-00-02 MPIO Other DS4K Array Disk


But it should show IBM MPIO DS4700 Array Disk


Where can I download the drivers for MPIO or RDAC ? will it be RDAC or sddpcm ?








AIX MPIO and SDDPCM multipath options with DS3000/DS4000/DS5000 常见问题解答 - 日志 - wolfsun - 开源SNS - Powered by UCenter Home

i read somewhere
Multipath I/O (MPIO) In AIX Version 6.1, the DS4K products are configured as Multipath I/O (MPIO) devices by default. A DS4K product using the FCPARRAY driver may be migrated to the MPIO driver by using the following instructions, or all DS4K devices may be migrated by uninstalling the devices.fcp.disk.array.rte package and then running the cfgmgr command or rebooting. The DS3K products are always configured as MPIO devices. There is no FCPARRAY support for these devices. The MPIO support for these devices removes the limitation of connecting only one adapter to each DS3/4K controller port.

so does this mean i have to uninstall devices.fcp.disk.array.rte to configure MPIO ?
