  • Ontap
  • ISCSI LUN
  • Veeam Proxy server with Windows v2019
  • EMC datastore

Issue

  • Existing LUNs were mapped to old Veeam Proxy server with windows v2019.
  • The LUNs from each volume were clubbed as single disk on host side and these disks were reporting as basic disks instead of dynamic disks.
  • New Veeam proxy server was created as there were some issues with old server and new server has same configuration, same IP and SAM IQN as old Veeam proxy server.
  • Since its same IQN for new server the existing LUNs on NetApp side must be visible on new Veeam proxy server but they weren't.
  • ISCSI initiator portal on new server was showing as connected for target LIFs.
  • New LUNs created on NetApp and mapped to the same Igroup were visible on both old & new server.
  • Old Veeam Proxy server was using Microsoft Storage Space Device and Spaces for existing disks on windows side as opposed to using iSCSI.
