Hi All,

I am configuring SAS Raid (5902 PCI-X DDR Dual – x4 3Gb SAS Raid Adapter) Controller on IBM power6 P520 (8203-E4A) but when I try configure Raid Level 5 on AIX, Hard drive not shown on Raid Controller but its shows on internal raid Controller I have 2x146 GB hard disk for Raid 1 and 3x 450 GB hard disk for Raid 5. Is there any way to configure this card as I already try to search but could not found any information regarding this card?

Please help me ASAP.

Regards,
Noman

Does your POWER6 520 have a split backplane? A split-backplane is required if you want the internal disks to be in two groups one controlled by the integrated SAS adapter and othe other controlled by a PCI SAS adapter. http://www-03.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/FQ123670.
