Problem with External Raid Controller.

Hi,

We have a Sunfire 4150 with On-Board Internal Raid Controller connected to 4 X 146 GB SAS disks.
This also has an External Raid Controller (Storagetek Eight-Port, External HBA
Model SG-XPCIESAS-R-EXT-Z) connected to a JBOD array ( Storagetek XTA2530 ) which has 5 X 300 GB Hard disk.

When the system is powered on The kernel of External Raid controller starts up first and after POST , it gives the message No drives found.

Next the Internal controller bios comes up and shows the 4 hard disks.

Now when we press Ctrl+A and get in to the Raid Controller Bios the internal controller shows all the 4 hard disks.

However the external controller does not show any drives at all.

Once we boot into Solaris or Linux and run Commn Array manager ( in out-of-band mode) it shows the 5 hard disks and allows us to create volumes. But after that
when we tried to create file systems it just hangs. We tried to create a small filesystem of 1GB. Even that is not going through in both Solaris and Linux.

Can some one help me please.

Thanking you all in anticipation

With warm regards
Ranjansukumar
