Business Critical Systems Technical Specialist/Consultant

Provides on-line and off-line technical support for the HP High Availability HA software namely MC/Serviceguard MC/SGeRAC aka MC/SG-OPS MC/SGeSAP Event Monitoring Service Hardware Monitors EMS HW Monitors Event Monitoring Service High Availability Monitors EMS HA Monitors Switchover HP-UX and Linux. Also provides technical support for the HA consultants in the areas of Serviceguard SGeRAC and SGeSAP cluster configuration including CVM in Serviceguard SGeRAC cluster environments .

• Serviceguard cluster configuration assessment Configure support and troubleshoot Serviceguard including SGeRAC SGeSAP MetroCluster and Continental Cluster cluster problems Integrate user applications in Serviceguard package environment Configure support and troubleshoot EMS HW/HA monitor resources in/out of Serviceguard cluster/package environment for monitoring system and cluster resources including CPU core I/O memory DIMMs disks storage enclosures network interfaces volume groups logical volumes file systems package rdbms Troubleshoots Serviceguard Manager GUI SGManager software problems Troubleshoots HP 9000/PA-RISC HP-UX versions /11iv1 11.23 and
• IA64/ILP HP-UX version 11.23/11iv2 11.31/11iv3 down systems with boot partitions being LVM and/or VxVM including boot failures HPMCs hangs and panics. Typical steps used to access unbootable systems includes
• Booting into LVM and/or VxVM maintenance to fix the corrupted LVM or VxVM structures and their links to the bootlif area on the boot disks regen new kernels and resolve console and/or network related configuration issues. Using the IgniteUX and/or Installation CD/DVD to boot into the recovery shell to fix corrupted bootlif replace/regen new kernels and other LVM or VxVM related problems affecting the boot process. Simulating and/or duplicating customer system problems in-house for troubleshooting
• Analyzes HP 9000/PA-RISC all versions of HP-UX and IA64/ILP versions 11.23/11iv2 11.31/11iv3 systems interrupts and crash dumps.
• Analyze TOC Transfer of Control and real/true hang causes involving hardware problems improper processor states example blocked interrupts deadlocks in the kernel code kernel starvation resource contention among threads and kernel resource depletion. Analyze perceived or degraded system performance issues involving spinlock contention or high interrupt rates real-time process starvation high CPU utilization and workload memory pressures and disk bottlenecks. Use HP s tools p4 or legacy q4 crashinfo kmeminfo and p4 to perform a thorough system crash dumps analysis of direct and indirect trap type leading to the panic hang or HPMC focusing on the specific trap type stack traces and the subsystems in question.
• Troubleshoots and implements Disaster Recovery and Fault Tolerance for HP-UX systems using Serviceguard Metro and/or Continental Cluster.
• Performs system installation configuration and administration of HP-UX and Linux operating systems. Also uses VxVM and LVM in the following areas
• Creating VxVM disk groups VxVM volumes LVM volume groups LVM logical volumes VxFS file systems and employ the use of mirroring and stripping. Addition and removal of VxVM volumes and LVM logical volumes Shrinking and extension of volumes and file systems sizes Replacement of disks migration of data from one disk device to another and monitoring of disk space usage Performance tuning Restore and backup both system and user data using HP s IgniteUX and other utilities Develop numerous shell/web scripts and using Perl Korn shell Bash shell Posix shell JavaScript C C Java Python and PHP languages to perform mail monitoring time tracking tracing system and user processes managing user accounts ... Establish patching schemes to get the systems and applications up to date using the Software Distributor tools on HP-UX and on Linux using rpm deb apt-get and yast2 Installed and Configured LANs including Direct Connect and assisted users interested in non-clustered file-sharing via NFS and Samba and also client-server module
• Troubleshoots Linux down systems hangs and panics.
• Use Knoppix recovery approach for troubleshooting boot failures root file system corruption defective disk problems disk partitioning and system recovery Use gdb and crash utilities for analyzing crash dumps involving hangs and other trap types leading to system panics
• Troubleshoots Trusted System and ACL related problems
• root and non-root user s password corruption incorrect permissions and ACLs on system specific binaries modify and/or updates user s protected password database settings

Develops applications using the shell scripting ksh sh-posix bash perl python and JavaScript C C and Java programming languages for the system interrupts team in the HP Customer Solution Center.

Assists other response center engineers to troubleshoot and resolve down systems boot failures hangs system interrupts/crash dumps online and offline crash dumps analysis High Availability HA clusters Serviceguard Serviceguard extension RAC Serviceguard extension SAP Serviceguard MetroCluster Serviceguard Extension CFS Serviceguard Extended Distance Cluster Serviceguard Continental Cluster and Event Monitoring Service EMS Hardware and High Availability Monitors software problems.
