Description of problem:
i have a Adaptec SCSI RAID 2120S adapter on my RHEL 4 system. the RAID volume's seem to be working
fine but there were problems with using the Adaptec RAID CLI application. the problems were resulting
from the fact that the RAID adapter device file (/dev/aac0) does not get automatically created. the aacraid
RAID driver version is '1.1.2-lk2 Apr 8 2005'. after manually creating the device file the CLI application
starts working fine.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. install RHEL 4 on a system with a Adaptec RAID adapter
2. check if RAID adapter device file (/dev/aac0) exists
Actual Results: device file does not exist which results in RAID CLI application not functioning.
Expected Results: device file should exist on the system.
here's some feedback from Arjan van de Ven:
"probably a driver issue in that in rhel4 devices get created by udev when they're registered in sysfs..."
As a workaround, you can put the aac0 device node in /etc/udev/devices. It will
be copied to /dev at boot time.
I will check with Adaptec about getting the feature added to the driver.
