Amrut Patil

Mainframe Storage Administrator with experience in managing enterprise z/OS storage environments, specializing in DASD management, SMS/DFSMS administration, backup & recovery, and disaster recovery operations. Hands-on experience in ACS routine management, storage provisioning, catalog administration, replication support, and DFSMShsm operations across Production and DR environments. Skilled in resolving storage-related incidents, space abends, backup failures, and supporting infrastructure changes including workload separation and storage capacity expansion.

Experienced with FDR, FDRABR, ADRDSSU, BCM replication, CA-1 tape management, and daily z/OS storage operations.

Analyst I at DXC Technology (2025-10 – Present)

• Managed enterprise workload separation, enabling cross-LPAR dataset sharing and executing complete Sandbox isolation.
• Developed and maintained ACS routines across all SMS constructs (Data Class, Storage Class, Management Class, Storage Group).
• Executed high-risk ICF Catalog resizing and reorganization utilizing IDCAMS EXPORT/IMPORT during critical windows to prevent structural limits and ensure catalog integrity.
• Performed storage capacity expansion by adding DASD volumes and updating replication (BCM) across Production and DR environments.
• Implemented StopX37 to intercept space abends (SB37/SD37), improving batch job stability and reducing manual intervention.
• Executed disaster recovery activities including replication-based DR and traditional DR.
• Managed DASD volume lifecycle, including allocation, expansion, and space monitoring across multiple LPAR environments.

Analyst 2 at DXC Technology (2023-03 – 2025-09)

• Performed DASD volume initialization and managed volume status changes, including onboarding volumes for DFSMShsm ML1 storage.
• Performed reorganization and resizing of DFSMShsm Control Data Sets (MCDS, BCDS, OCDS).
• Modified Primary Space Management (PSM) execution timings to optimize space management cycles.
• Executed dataset and volume-level recovery using DFSMSdss (ADRDSSU) and FDRABR.
• Resolved backup failures by coordinating with IBM/BMC vendors and modifying FDR archival rules.
• Managed CA-1 tape operations including scratch processing, expiry management, and lifecycle control.
• Conducted daily BAU health checks for storage groups, ICF catalogs, and tape scratch counts.
