I am using 3ware RAID cards on all my servers. Is it possible to get ISPconfig 3 to access the RAID info from the 3ware? At the moment I'm getting a message: mdadm is not installed. mdadm is for sofware RAID, but not for hardware RAID like my 3ware cards.
You will have to write a modified monitoring plugin for that. The current plugin does not support 3ware.
The monitor module is maintained by oliver (forum user "vogelor"), if you find out how the raid status of your 3ware raid can be queried on the shell he might be able to integrate this in the monitor module.
tw_cli is the command line app you are looking for. There's a debian package floating around for it (don't have the link for it at the moment), or you can download it directly from 3ware.
Yes. Sorry for the delay. I did not want to test all this stuff on my production servers. At the moment I'm building a new server, and got the "tw_cli" working on it. I'm looking forward of testing your code.
