ONTAP SAN SCSI errors in new ESXi setup with iSCSI connection
Applies to
- ONTAP 9
- VMware ESXi
Issue
- During initial setup of VMware ESXi with ONTAP iSCSI targets SCSI errors are encountered
- Changing the VMware path selection policy (PSP) to fixed failover policy prevented further errors
- VMware host virtual switch iSCSI vmkernel port has two vmnic uplink ports configured in active /active teaming and failover policy
