Why I am getting "Disk not detected" error when trying to install RHEL7 on HP Proliant BL360 G5?
Environment
- Red Hat Enterprise Linux 7.1
- HP Proliant BL360 G5
- Anaconda
Issue
- Why I am getting "Disk not detected" error when trying to install
RHEL7
onHP Proliant BL360 G5
? - While installing RHEL7 on
HP Proliant BL360 G5
, the local hard disk is not detected. We have configured RAID 5 on my server with 3 disk.
Resolution
- Append the anaconda command line parameter "hpsa.hpsa_allow_any=1" to resolve the issue.
- Also add this parameter in
grub.cfg
file as well after installation. hpsa
is aSCSI driver
forHP Smart Array RAID controllers
.- From the man page:
hpsa_allow_any=1 option allows the driver to attempt to operate on any HP Smart Array hardware RAID controller, even if it is not explicitly known to the driver. This allows newer hardware to work with older drivers. Typically this is used to allow installation of operating systems from media that predates the RAID controller, though it may also be used to enable hpsa to drive older controllers that would normally be handled by the cciss(4) driver. These older boards have not been tested and are not supported with hpsa, and cciss(4) should still be used for these.
Root Cause
- RHEL7 removes the old CCISS module which is why the disk was not getting detected.
