Due to storage misconfiguration some servers lost their SAN LUNs for a while. Due to that they needed a reboot. All in all, the following servers were booted:,, and

All pending updates were installed as well. Also more hardware resources were allocated to

Update at 17:37 by Pekka Tonteri: All services are up and running.

Implantable Medical Devices (IMDs) such as pacemakers, drug pumps, implantable cardioverter defibrillators (ICDs), and neurostimulators are becoming commonplace. Currently, IMDs use plain-text protocols to communicate using wireless over short-range ranges. Remote monitoring of vital health parameters over a long period of time can enable physicians to make more accurate diagnosis and provide better treatment. But those connectivity design emerges important issue of security.

Break in file server at 2013-02-14 16:58 - 20:36

HIIT's file server first partially stopped responding to SMB requests and soon after that also NFS traffic slowed down. Due to that and longish uptime the server was rebooted.

Pending operating system and firmware updates were also planned to be installed.

Update at 20:56: File service and all services depending on it are up and running. Firmware updates were skipped due to server being somehow in a weird state; firmware update hung (quite likely the first time ever). To reset the server it was removed and reinserted to the blade enclosure. Hopefully this fixes slow performance in remote management (iLO2).
