CMU version 7.2
Backup/Clone target:
SL4540 Gen8 running RHEL 6.4 x86_64
BIOS: 2/10/2014
B120i: 4.50
iLO: 1.50
When trying to backup one of the SL nodes, the system successfully reboots, pxe boots, and then goes into an endless loop of various Call Trace outputs and USB disconnect/uhci_hcd events (see attached screenshot)
The backup job eventually times out and fails, but the SL node continues in this endless loop
I have blacklisted ahci as suggested in the user guide for the B120i controller.
I have also blacklisted hpsa to prevent the P420i controller from loading
When kicking off the backup job, I select sda partition 3...this is where the / partition resides
Has anyone run into an issue like this?
Any suggestions?
Solved! Go to Solution.

Re: SL4540 Gen8 backup/clone problem
Hello Ryan,
Is this a internal cluster or customer cluster ?
If it is a customer cluster, please raise support call at local hp support center.
Is this node has Mellanox cards ? If yes, what is the firmware version ?
I couldn't find the screen shot attached. Can you please attach it again, when you see the stack traces.
Regards,
Abhishek Chintala
