apama{001,002}
Summary
apama001 and apama002 are two nodes in an HP SL4540 Gen8 chassis. apama001 is installed with Xenial and apama002 is installed with CentOS 7.2 and using download.ceph.com as its source for ceph packages.
Both hosts are serving as OSD nodes for the longrunningcluster.
The iLOs are accessible but the java KVM is mostly useless since our lack of Enterprise License causes it to quit after POST.
The systems were updated to latest firmwares (2016.04.0-SPP2016040) the week of 1MAY2016 using hpsum on CentOS.

These also have 10Gb SFP+ ports that are cabled but may need switch port configuration. Probably useful to have before re-adding to cluster.
Quirks
I was able to install Fedora23 on apama001 but still got Red Screen of Death and “Illegal Opcode” after grub tries to boot the OS. Something about rpm-based distros doesn't like searching for the root partition using UUID.
What fixed it was finding the proper root drive and manually booting to it in a grub rescue prompt. See below.
grub> ls (hd0,msdos1)/boot vmlinuz-4.2.3-300.fc23.x86_64 System.map-4.2.3-300.fc23.x86_64 config-4. 2.3-300.fc23.x86_64 initramfs-4.2.3-300.fc23.x86_64.img initramfs-0-rescue-ba8d c4c42e5a4ec483a635961112dfd8.img vmlinuz-0-rescue-ba8dc4c42e5a4ec483a635961112d fd8 initrd-plymouth.img grub> set root=(hd0 <tab> Possible partitions are: Device hd0: No known filesystem detected - Sector size 512B - Total size 488386584KiB Partition hd0,msdos1: Filesystem type ext* - Last modification time 2016-05-03 18:11:21 Tuesday, UUID 4390d2e3-3154-4855-8ad4-8417c430d982 - Partition start at 1024KiB - Total size 488385536KiB grub> set root=(hd0,msdos1) grub> linux /boot/vmlinuz-4.2.3-300.fc23.x86_64 root=/dev/sda1 grub> initrd /boot/initramfs-4.2.3-300.fc23.x86_64.img grub> boot
For CentOS, this had to be modified a bit:
grub> set root=(hd0,msdos1) grub> linux /vmlinuz-3.10.0-327.el7.x86_64 root=/dev/**sdz3** console=ttyS1,115200 grub> initrd /initramfs-3.10.0-327.el7.x86_64.img grub> boot
There's probably a permanent fix that can be applied in grub.cfg but haven't looked into it.
