Note: This is the page for the NEW EINSTEIN - 8 core server from Microway

The previous einstein hardware is described in the previous page for Einstein at old einstein

New Microway Server

The new einstein is a 2 quad-CPU server in a 2U rackmount chassis put together nicely by Microway. It arrived at UNH on 11/24/2009. The system has an Areca RAID card with ethernet port and an IPMI card with ethernet port. The motherboard is from Super Micro. Details need to be put here!


Important things to remember before this system takes on the identity of Einstein

  1. The ssh fingerprint of the old einstein needs to be imported.
  2. Obviously, all important data needs to be moved: Home Directories, Mail, DNS records, ... (what else?)
  3. Fully test functionality before switching!

Configurations Needed

  1. RAIDs need to be setup on Areca card.
  2. Mail system needs to be setup
  3. Webmail needs to be setup. Uses Apache?
  4. DNS needs to be setup.
  5. Backup needs to be made to work.
  6. rhn_config - I tried this but our subscriptions seem messed up. (Send message to customer support 11/25/09)

Initialization

Server arrived 11/24/2009, was unpacked, placed in the rack and booted on 11/25/2009.

Initial configuration steps are logged here:

  • Initial host name is gourd (gourd.unh.edu) with eth0 at 10.0.0.252 and eth0.2 (VLAN) at 132.177.88.75
  • The ARECA card is set at 10.0.0.152. The password is changed to the standard ARECA card password, user is still ADMIN.
  • The IPMI card was configured using the SuperMicro ipmicfg utility. The net address is set to 10.0.0.151. Access is verified by IPMIView from Taro. The grub.conf and inittab lines are changed so that SOL is possible at 19200 baud.
  • The LDAP configuration is copied from Taro. This means it is currently in client ldap mode, and needs to be change to an ldap server before production. You can log in as yourself.
  • The autofs configuration is copied from Taro. The /net/home and /net/data directories work.
  • The sudoers is copied from Taro, but it does not appear to work.
