Problem

The PowerMax volume populator currently fails when creating a masking view with error:

A problem occurred creating the masking view resource: Error for: 000120001473 / xcopy-0e6543f1 : The operation can not be performed because of a mismatch between the initiator and the director port

Root Cause

The code uses a port group name from the POWERMAX_PORT_GROUP_NAME environment variable without validating its protocol type. When the port group's protocol (e.g., Fibre Channel) doesn't match the initiator type (e.g., iSCSI), the masking view creation fails.

Location

cmd/vsphere-xcopy-volume-populator/internal/powermax/powermax.go:
- Line 182: CreateMaskingView call
- Lines 91-150: EnsureClonnerIgroup function
- Line 249: Port group name retrieved from env var without validation

Solution Required

1. Fetch port group protocol using GetPortGroupByID() API:
   • The PortGroup struct contains PortGroupProtocol field (values: "iSCSI", "SCSI_FC", "NVMe_TCP")
2. Select appropriate initiators based on protocol:
   • For PortGroupProtocol == "iSCSI": use iSCSI initiators (IQN format)
   • For PortGroupProtocol == "SCSI_FC": use Fibre Channel initiators (WWN format)
3. Validate compatibility before creating masking view

Related Code Comment

Line 106 contains a TODO that was never implemented:

// 5. add port group with protocol type that match the cloner IQN type, only if they all online

API Reference

• GetPortGroupByID(ctx, symID, portGroupID) returns *types.PortGroup
• PortGroup.PortGroupProtocol field contains protocol type
