Promise Pegasus Daemon Cannot Start
Mac Mini Server with the new Thunderbolt compatible Promise Pegasus R6 RAID array. The solution is effectively plug-and-play. You turn on the RAID, plug in the Thunderbolt cable, and a new hard drive shows up on your Mac. While not required, the Pegasus comes with the “Promise Utility” that allows you to monitor your RAID. I’m a sucker for little toys like this, so I installed it… and was very disappointed when it didn’t work.
Every time I launched the Promise Utility, it told me that the daemon wasn’t running and to press OK to restart it. No matter how many times I tried, it never started. I tried a good old fashioned reboot (of both pieces of hardware), but still no luck. I even went to Promise’s site and tried downloading the software again (assuming that which I installed was out of date and not 10.7 compatible). No dice. The last thing I did was launch terminal and check /var/log/system.log, going back to my Linux roots. There it was:
<br /> Aug 25 17:49:03 server-1 com.promise.httpd: httpd: apr_sockaddr_info_get() failed for server-1.hq.companyname.com<br /> Aug 25 17:49:03 server-1 com.promise.httpd: httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName<br /> Aug 25 17:49:03 server-1 com.apple.launchd (com.promise.httpd): Exited with code: 1<br />
sudo nano /etc/hosts and on the line that reads “127.0.0.1 localhost”, I added “server-1 server-1.hq.companyname.com”. Of course, you’ll want to change that to read the name of your server. If you don’t know the name of your server, simply run hostname from the terminal command prompt.
After that, I clicked on Promise Utility again and away it ran. Since the Pegasus R6 comes preconfigured out of the box as a RAID 5, there wasn’t really any configuration for me to change. At least now I can get into the utility, down the line, to check on the unit status and verify everything is operating properly.
