VMAX Initiator Group Port Flag Overrides

I'm trying to get a global view of all flag overrides without having to crawl every IG and output one by one in a loop (very slow if many IG's).

With  symaccess list view -detail -sid XXXX  this shows every Masking View, and additionally shows every child initiator group, so if we have

MV_cluster    with sub child initiator groups  IGC_server1 and IGC_server2, then list view -detail will show *3* full entries

1 - the full MV with child groups listed in the IG section

2 - again, the full MV, this time with IGC_server1 actual WWN's listed in the IG section

3 - again, the full MV, this time with IGC_server2 actual WWN's listed in the IG section

So this is great, and I can get all information pertaining to all Masking Views into an output file, or output to XML and parse later.

But, the problem is that I need to collect all port flag overrides information for all IG's, which can be done via the specific command for that IG as below. What I would like is a full listing that shows every flag override for every WWN in every IG. Commands like list view -detail, suggest that this should be possible (obviously I can run a loop to run all of these commands, and I could do that to collect Masking View info also, but that's *hugely* slower than the list view -detail to get everything in one sweep). Would appreciate if anyone has a way to collect this info efficiently (parts in red are specifically what I am interested in collecting globally for an array - maybe some long format XML output includes this that someone knows as sometimes that outputs different information from the non-XML output?)? Thanks.

You can use the symcfg list command to list configuration and status information for a specific director type. For example, to list information about all fibre channel (-FA) directors on Symmetrix array 000198700230, enter: symcfg list -fa all -sid 230 Symmetrix ID: 000198700230 (Local) S Y M M E T R I X F I B R E D I R E C T O R S Dir Port WWN Flags Max AVPFG Speed FA-7E 0 5000097300039918 ..X.. 8 FA-7E 1 5000097300039919 ..X.. 8 FA-8E 0 500009730003991C ..X.. 8 FA-8E 1 500009730003991D ..X.X 8 FA-9E 0 5000097300039920 ..X.. 8 FA-9E 1 5000097300039921 ..X.. 8 FA-10E 0 5000097300039924 ..X.. 8 FA-10E 1 5000097300039925 ..X.. 8 FA-9F 0 5000097300039960 ..X.. 8 FA-9F 1 5000097300039961 ..X.. 8 Legend: Flags: (A)CLX Enabled : X = True, . = False (V)olume Set Addressing : X = True, . = False (P)oint to Point : X = True, . = False (F)COE Director : X = True, . = False VNX (G)ateway Direct Attach : X = True, . = False Note: The VNX (G)ateway Direct Attach Flags column in the above Legend only displays for Solutions Enabler V7.6 and higher.

Normaly, you have the flags por all initiator in the same port. The command for see all flags in thoses ports is: symcfg list -fa all -sid xx

OP is asking about viewing port override flags, not flags set on the FAs.

The CLI command "symaccess show -type init -detail" is the only command that will expose the Port Override flags. Looping through each IG will take a little time as suggested. It will also be quite chatty to the array. I suggest if you want to run the show for each IG, it would be good to take a copy of the symapidb file (run symcfg sync -masking first) and access it in offline mode (will likely be faster in offline mode too).

To run in  offline mode, set the following environment variables:



Then you can do something like this (windows):

for /F "tokens=1" %a in ('symaccess -sid 99 list -type init') do (symaccess -sid 99 show %a -type init -detail)

Note if the command is in a batch file, you need %% and not %.

The other possibility is to use the Unisphere REST API. You can obtain a list of Initiators that have Port overrides set in a single get operation. Then it would be a get for each initiator in the list to obtain the override flag values. No single GET command though to obtain the information you are after.
