I have a HP DL320e g8 v2 server running CentOS 7.1 (kernel 3.10.0-229.4.2.el7.x86_64). The onboard B120i SmartArray was disabled, and a PCI-Express P212 SAS HBA was installed with two identical 3TB Seagate disks in RAID-0 on the internal SAS port. The system boots perfectly.
But I have a HP Tape Library (MSL 1/8 G2) with Ultrium LTO-4 driver, and I need to plug it on the external SAS port of the P212. When I plug it, the system doesn't boot. I got a Kernel Panic.
If I unplug the SAS cable of the external port, the system boots again...
Can I use both ports of P212 (internal and external) at the same time?
I need to configure something on the controller? or on the Bios?
Because of performance reasons, I can't use the onboard SmartArray controller... I need to use the P212, if it supports the two ports at the same time.
Note: P212 has read cache enabled, and write cache disable. It has 256 MB memory with no batery.
