Monitoring LSI RAID adapter with mpt-status

Monitoring LSI RAID adapter with mpt-status

Download and install the mpt-status utility:

# wget http://www.drugphish.ch/~ratz/mpt-status/RPMS/1.2.0_RC7/mpt-status-1.2.0_RC7-3.i386.rpm
# rpm -ivh mpt-status-1.2.0_RC7-3.i386.rpm

So far, so good. But running the mpt-status led into some error messages:

# mpt-status
open /dev/mptctl: No such file or directory
Try: mknod /dev/mptctl c 10 220
Make sure mptctl is loaded into the kernel

Ok, there are two errors, first I solved the first error:

# mknod /dev/mptctl c 10 220

Let’s try again to run the mpt-status utility:

# mpt-status
open /dev/mptctl: No such device
Are you sure your controller is supported by mptlinux?
Make sure mptctl is loaded into the kernel

One of the error messages disappeared, but still, it is not working. Now you have to load the mptctl module:

# modprobe mptctl

Try again to run the mpt-status utility, you will see it will work. Enjoy!
