Administered / managed
approximately 500 TB of data in a parallel Sysplex (multiplex) environment.
·
Primarily worked
independently on all projects, spear headed the UCB reclamation project to
reduce the number of unit addresses in the environment by reconfiguring all IBM
DS8300 old volumes (mod3, mod9) with higher density volumes (mod-27, mod-54),
thus minimizing the number of mod-3s and mod-9s addresses
·

data moves from low density drives to higher density drives, oncall support for
after hours, perform catalog work, building aliases, performing merge cats,
enlarging catalogs, perform disaster recovery drills, assisted with the testing
of z/OS 1.9 to z/OS1.10 implementation, working on multiple parallel sysplex
environments with DFSMS, HSM, TDMF, CA-VANTAGE, CA1

linklisted libraries and APF libraries for volume movement
·
Developed the NEW
UCB addresses scheme on new DS8300 disk boxes / devices and coordinating the HCD
gens with the systems programmers
·

on migrating off of old disk devices EMC DMS2000 to the new DS8100 and DS8300
devices, worked hand in hand with the PPRC data replication folks to ensure
that data mirroring is not disrupted while performing disk moves
·
Monitored and
worked with GDPS to disable Hyperswap, wrote procedures for storage management
on volume allocation in the PPRC environment, and procedures for maintaining a
proper disk balance of DFSMS pools across all of the disk subsystems for
performance and I/O reads and writes, mentored teammates on the use of TDMF and
IBM Utilities, JCL, and storage management functions.
