◆ V (Volume Set Addressing) When enabled along with the Disk_Array flag for HP-UX hosts, the volume set addressing mode is selected. VSA mode allows octal addressing. ◆ C (Common Serial Number) This flag should be enabled for multipath configurations or hosts that need a unique serial number to determine which paths lead to the same device.  Disable      Queue Reset on Unit Attention (D)  Disable_Q_Reset_on_UA  When enabled, a Unit Attention (UA) that is propagated from another director does not flush the queue for this device on this director. Used for hosts that do not expect the queue to be flushed on a 0629 sense (only on a Hard Reset).  Environ_Set - E :: When enabled, this flag enables the environmental error reporting by the Symmetrix to the hoston the specific port.  Avoid_Reset_Broadcast:   [ARS] :: When enabled, a SCSI bus reset only occurs to the port that received the reset (not broadcast toall channels).  AS400  [AS4] :: This flag should be enabled for any AS400 (iSeries) hosts connecting to the port.  OpenVMS  [OVMS] :: Enabled for an OpenVMS fibre connection.  SCSI_3  [SC3] :: When enabled, the Inquiry data is altered when returned by any device on the port to report thatthe Symmetrix supports SCSI 3 protocol. When this flag is disabled, the SCSI 2 protocol issupported.  SPC2_Protocol_Version  [SPC2]  :: This flag should be enabled (default) in a Windows 2003 environment running Microsoft HCT testversion 12.1. When setting this flag, the port must be offline.  SCSI_Support1  [OS2007]  :: When enabled, this flag provides a stricter compliance with SCSI standards for managing deviceidentifiers, multi-port targets, unit attention reports, and the absence of a device at LUN 0.
  Can you please clarify or provide the documentation on below port flags to know the purpose of each flag When we have to the set the port flag, when to not set the port flags.
