Thursday, 01/01/2015, was the New Year Holiday. We provided minimal coverage consisting of one Computer Operator per 8-Hour Shift to respond to system prompts, environmental alarms, and telephone calls. The UCHIBETA LPAR was available for Open Testing from 8:00 AM until 5:00 PM under z/OS 1.13 with its full complement of Online Regions available.

03/15/2015

The Mainframe Team had test time for Sunday, March 15 starting at 7am to allow IBM time to install hardware maintenance to the IBM z9 Mainframe (CHG0028805). A few of the patches addressed a new GHOST glibc security vulnerability (CVE-2015-0235) on the mainframe's Hardware Management Console (HMC) and Support Element (SE). The UCHIMVS1 (Production) LPAR was unavailable to users and scheduled ESP events during this time. We did a power on reset and IPL UCHIMVS1 after the work was completed. Communication was sent out once the system was again available to all.

We did not IPL the UCHIMVS1 LPAR on the morning of Monday, March 16, 2015.
