# Set port flags

Unisphere provides monitoring and management for Internet Small Computer Systems Interface (iSCSI) directors, iSCSI ports, iSCSI endpoints, IP interfaces, and IP routes.

## Prerequisites

The iSCSI endpoint must be in an offline state before the flags can be modified.

## Steps

1. Select a storage system.
2. Select System > iSCSI to open the iSCSI dashboard.
3. Click iSCSI Endpoints (Attached or Unattached).
4. Select an iSCSI endpoint and click Set Port Flags.
5. Select one or more of the following Port Flags:

   Volume Set Addressing | Enables the volume set addressing mode. When using volume set addressing, you must specify a four-digit address in the following range: (0)000-(0)007, (0)010-(0)017, and so on, to a maximum of (0)FF0-(0)FF7. The first digit must always be set to 0 (the storage systems do not currently support the upper range of volume set).
   Environ Set | Enables the environmental error reporting by the storage system to the host on the specific port.
   Avoid Reset Broadcast | Enables a SCSI bus reset to only occur to the port that received the reset (not broadcast to all channels).
   Disable Q Reset on UA | When enabled, a Unit Attention (UA) that is propagated from another director does not flush the queue for this volume on this director. Used for hosts that do not expect the queue to be flushed on a 0629 sense (only on a hard reset).
   Soft Reset | Supports SCSI soft reset on a port when enabled for a Bull GCOS-7 host.
   SCSI 3 | Alters the inquiry data (when returned by any volume on the port) to report that the storage system supports the SCSI-3 protocol. When disabled, the SCSI-2 protocol is supported.
   SCSI Support1 | Provides a stricter compliance with SCSI standards for managing volume identifiers, multiport endpoints, unit attention reports, and the absence of a volume at LUN 0.
   SPC2 Protocol Version | This flag should be enabled (default) in a Windows 2003 environment running Microsoft HCT test version 12.1. When setting this flag, the port must be offline.
   Open VMS | Enables an Open VMS fibre connection.
   ISID Protected | Protected initiator session identifier. This flag applies to iSCSI endpoint only. It has no effect for FA/FCoE ports. When this flag is set on iSCSI endpoint, the system uses the ISID and iSCSI name to calculate the World Wide Name (WWN) in the Persistent Group Registration (PGR) record.
