I have a Cisco 6509 switch that I'm monitoring with SNMP from a CentOS5 machine. SNMP polls are the only access I have to this device, we are not allowed to log on via telnet.

Hi All, I've been chasing down a problem with LUN masking on CentOS5/RHEL5 hosts with QLogic HBA's for a few hours and seem to have got to an impass; Any device (disks in my case) on Non-sequential LUN's are not registered with the OS.

Hi All, I've a quick question I'm hoping someone can help out on; One of our NFS servers has an intermittent hard lock problem under high load. This is a CentOS 5.7 box. It's due for replacement sometime next year. However...
