How do you unconfigrue RDAC on aix 5.3 TL10. I will use the new driver pcm.
Do you I just need to varyoff the vg and export the vg and then install sddpcm filesets reboot ? or do we need to uninstall rdac ? or unconfigure it ?

I can;t find any document about it.

Thanks in advance for any help

Cheers
Al

Are you moving off DS4000 disk to some other type? If not, as far as I know rdac is required. If you are moving to a different disk type then you would need to load the required driver support for that disk type, migrate the data then unconfigure the DS4000 disks and remove the rdac device driver.

If you want to change from RDAC to native AIX MPIO then follow this guide.

You can also use the IBM SDDPCM Driver for IBM DS Storage.
Here you will find Instructions how to use IBM SDDPCM Hostattachment Script and SDDPCM with AIX MPIO.
http://www-01.ibm.com/support/docview.wss?uid=ssg1S4000201

I recommend to read the interoperability matrix and the readme files carefully, there are some pitfalls with SDDPCM and VIOS and HACMP.

Hi

I am keeping my disks on SAN DS4800. Checking on the matrix support SDDPCM is supported with DS4800 required min 5.3TL6.

I will have a look to this document.

Thanks
