Sr. Unix Administrator
Built server in AIX Environment using Technical Platform: IBM P570, AIX 5.3 o Created the LPAR definitions and assigned the resources on HMCs and built the LPAR with AIX 5.3.Configured the etherchannel for redundancy for NIC/SWITCH failure. o Tuned the kernel parameters for webservers. o Configured the SAN disk and created the file systems. Confidential,, Boston, MA 2004 – 2008
Sr. Unix Administrator
Implemented regional Highly Available (HA) project for AIX Environment using Technical Platform: IBM P590, AIX 5.3, Veritas cluster server 4.0. o Provided a Highly Available regional diversified server infrastructure for AAA applications and databases. o Created the LPAR definitions and assigned the resources on HMCs and built the LPAR with AIX 5.3. o Configured the etherchannel for redundancy for NIC/SWITCH failure. o Tuned the kernel parameters for oracle and Sybase servers. o Configured high availability using VCS. o Configured the SAN disk and created the file systems. o Test the failover and work with business unit to migrate to new servers. Migrated LPAR from existing frame to another standalone frame o Increased capacity by 40% and improved performance through moving database server from one P570 frame to another stand alone frame. Built the new LPAR using the mksysb image of current LPAR. Exported and vary-off the volumes on existing LPAR and import and mount the LPAR on new LPAR. Converted from AIX 5.2 to AIX 5.3 Brief Description Rebuild the existing 5.2 servers with 5.3 access the same SAN storage with minimal Business Impact using Technical Platform: IBM P690, AIX 5.2, AIX 5.3, EMC Powerpath 4.2.2. Setup and configured VVR on production application servers on different sites. Using Technical Platform: Sunfire v1280, solaris 8.0, Veritas volume manager 4.0, Veritas file system4.0, veritas Volume replicator 4.0. Migration from Veritas volume manager to Sun Disk Suit using Technical Platform: Solaris 8, Veritas volume manager 3.5, Sun Disk suit 4.2.2. Provided day-to-day technical support and including the following projects: Server Resiliency: For assigned servers achieve server resiliency using Etherchannel in AIX, IPMP for Solaris and Bonding for Linux. Increased capacity on live AIX server by adding cpu and memory to a live LPAR using DLPAR. Add/remove/replace Uniboards on 6800 servers with running Solaris OS. Set-up Linux server: Installed and administered P servers running RHEL 2.1/3.0/4.0 via kickstart. Supported HA HACMP and VCS for AIX and VCS for Solaris. Confidential,Boston, MA 2000 – 2004
