mira
Summary
We have 122 mira hosts. Some serve as vpshosts hypervisors and some serve as OSD nodes in the longrunningcluster. The remaining nodes are used as baremetal testnodes.
See the [long-running-cluster] and [vps_hosts] groups in ceph-sepia-secrets Ansible inventory to see what systems are used for.

Areca RAID Controllers
Flashing Firmware
The latest firmware for ARC-1222 controllers can be obtained from here.
The latest firmware for ARC-1880 controllers can be obtained from here.
My process for flashing ARC-1222 firmware manually is below. This assumes you've downloaded and extracted the firmware zip. The same process can be used for other Areca controllers. Just use the proper firmware BIN files.
scp /home/dgalloway/BIOS/areca/ARC1212_1222/ARC1212* ubuntu@$host.front.sepia.ceph.com:/home/ubuntu/ ssh $host sudo -i for file in $(ls /home/ubuntu/ARC1212*.BIN); do cli64 sys updatefw path=$file; done for file in $(ls /home/ubuntu/ARC1212*.BIN); do rm $file; done
