Hi Stuart,  I dont know about your array microcode.But please go through this to get an idea--  EMC strives to make setup and operation of our products as simple and easy as possible.  We believe that Enginuity 5875 for VMAX is delivered to you with correct default port flag settings for most users and that few or no changes will be needed during installation of your new system.  Here is a summary of the default flag settings for the most popular operating systems. and changes required by some of those operating systems.        2. What Servers can connect to 5875 Enginuity without changing Port Flags?  Operating Environment  Port Settings EMC Celerra  Enable 'ARB' and 'D' flags IBM AIX  5875 Defaults, Unchanged  INM i  Enable 'AS4' flag  LINUX  Enable 'D' flag  Hewlett-Packard OpenVMS  Enable 'OVMS' flag  Hewlett-Packard True64  Enable 'OVMS' flag, Disable 'SC3 flag  Hewlett-Packard HP-UX 11i V1 &V2  Enable 'V' flag, Disable 'SC3' and 'OS07' flag  Hewlett-Packard HP-UX 11i V3  Enable 'V' flag, Disable 'SC3'  Microsoft Windows Server 2008  5875 Defaults, Unchanged  Microsoft Windows Server 2003  5875 Defaults, Unchanged  Oracle Solaris  5875 Defaults, Unchanged  VMware ESX  5875 Defaults, Unchanged     3. What are some additional considerations?     4. Port Flag usage notes:  For additional information regarding to port flags, specific flags for a given server, impacts of changing flags and any other known issues, please go to EMC.com and search PRIMUS for additional port flag information.    5. How did 5875 Enginuity Port Flag Defaults Change from earlier releases?  The following is the table of default settings for the commonly set flags for 5875 Enginuity versus other recent Enginuity releases:   Flag  Enginuity 5773   Enginuity 5874   Enginuity 5875 PP  Enabled  Enabled  Enabled  UWN  Enabled  Enabled  Enabled  EAN  Enabled  Enabled  Enabled  C  Enabled  Enabled  Enabled SPC2  Enabled  Enabled  Enabled  OS07  Disabled  Disabled  Enabled  ACLX  Disabled  Disabled  Enabled  SC3  Disabled  Disabled  Enabled    6. What are the port flag descriptions?  Flags come in two types.  The first type are flags set only on the array’s storage port. These flags affect the connectivity behavior of all servers connected to that port.  The second type of flags can be set per storage port or initiator group, a group defined on the array as one or more initiators (HBAs) for a given server.  With this type, the flags settings for the initiator group override, for the group, the settings on the port itself.  In this way, a port can be shared by servers with different flag requirements.  The following table list where the flags should be set:  Flag  Flag Description Flags set only at the Storage Port Flags that can be set at the Storage Port or Initiator Groups PP When enabled, specifies a point-to-point (direct or switched) topology in the initialization sequence. When disabled (default), it is initialized as an arbitrated loop.  YES  N/A  EAN When enabled, allows two fibre ports to handshake and settle on an optimal speed for data transfer.  YES  N/A  ACLX When this flag is set, it enables the Initiator Groups/Access Logix1 function on the port.  YES  N/A  UWN When enabled, ensures unique World Wide Names (WWNs) within the fibre environment by incorporating Symmetrix serial numbers and port numbers for each WWN. Enabled by default for all environment configuration changes and new environments. When disabled, WWNs do not have to be changed.  YES  N/A NP When enabled along with the Hard Addressing flag, the Fibre Channel director only uses hard-assigned addressing when it initializes the loop, otherwise, soft-assigned addressing is used during loop initialization (the default).  YES  N/A  C When enabled, this flag causes the serial number of a specific volume to be the same regardless of the port on which it is visible.  N/A  YES  V When enabled along with the Disk_Array flag for HP-UX hosts, the volume setaddressing mode is selected. VSA mode allows octal addressing.  N/A  YES  ARB Typical behavior on a SCSI bus reset is to propagate the reset to all channels that share devices mapped to the port that received the reset. When this bit is set, the reset only occurs to the port on which it is received, and is not broadcasted.  N/A  YES  D When this flag is 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 SCSI 0629 sense (only on a Hard Reset).  N/A  YES  SC3 When this flag is set, it alters the Inquiry data returned by any device on the port to report that Symmetrix supports SCSI -3. If this flag is not set, it reports that SCSI-2 is the supported protocol. This flag also enable the support for Auto Contingence Allegiance which is required by IBM AIX.  N/A  YES  OS07 The effect of the OS07 setting can be summarized as follows: 1. Automated device discovery of newly configured devices and/or device paths. 2. Automated creation of DSFs (device special files) for newly configured devices. 3. Automated detection and adaptation of device attribute changes including LUN 4. Capacity change event.  N/A  YES SPC2 This flag enables the support for SPC-2 SCSI standard that are recommended for FC, FCoE, and iSCSI connectivity  N/A  YES  AS4 This flag should be enabled for any AS/400 (IBM i) hosts connecting to the port.  N/A  YES  OVMS Enabled for an OpenVMS Fibre Channel connection.  N/A  YES
All:  The E-Lab Navigator says that the OS2007 FA Port Flag Bit is "optional" in Linux configurations, but it doesn't say optional for what?  How do I find that?  There are no footnotes, which sometimes there are.  I searched in PowerLink, but I can't find an answer.  I did find that somebody had asked this very same question for VMware, but I didn't get a good answer there, either.  I was referred to Primus emc173498 and emc71378, which told me, respectively, that the OS2007 flag is required in HP-UX 11v3 for automatic device discovery, and has something to do with port sharing in heterogenous environments (whatever that means) on VMware.
