Adding EMC SRDF Adapter for VMware SRM fails

[MikeErter]

Hi Community,

We have DMX storage in the protected site and recovery site. We're trying to setup the array manager for SRM.

Adding the array manager is failing with the error below; hoping someone has sorted this out and can offer some guideance.  Thanks!

Add Array Manager

Unable to add array manager.

SRA command 'discoverArrays' failed. Failed to connect to the array management host.

Please check EmcSrdfSra logs for more information on the error.

This is the exact error that I am getting,  so I am going to hijack your post

in My case we have two DMX-4  we are using SRM 5.0 ad the latest EMC SDRF SRA, and solution enabler 7.5 (32bit)

in my clients environment they have no SYMAPI servers that are at the required level so I am attempting to configure the 7.5 Solution enabler Virtual appliance to handle this role.

I am getting confused as I am not sure where the disconnect it. Is it at the SRM server end or the SYMAPI Virtual appliance.

When I am on the appliance I can see it can See the Arrays, however I do not know if they are configured correctly, so I cannot rule them out as the cause of the issue.

I'm assuming that you did have a look at the EmcSrdfSra log files as the error suggested. Does that show any errors in the actual array discovery process? Do you have a Solutions Enabler host set up, and what does a "symcfg disco" give as output?

It should be noted that the SRDF SRA version 5.1 no longer supports DMX arrays--VMAX only. If you are using DMX arrays you must remain with the SRDF SRA version 5.0.1.0.

Hi Mike,

you should read the following documents provided on Powerlink.

Using EMC SRDF Adapter for VMware vCenter Site Recovery Manager 4.1

Using EMC SRDF Adapter for VMware vCenter Site Recovery Manager 5.0

And without further info I would simply recommend to open a SR at EMC.

I'll be releasing the updated version of the techbook very shortly and it has a lot more information about configuring Solutions Enabler. All of the common things that seemed to trip people up earlier are better explained (hopefully) in the upcoming version.

[TomHowarth]

Cody, I am only using SRM 5.0

[codyhosterman]

Yeah but you said you were using the latest adapter which is the SRDF SRA version 5.1 which works with SRM 5 and 5.1. Which adapter version are you using?

[kastlr]

Hi Tom,

there're some booby traps when using the SE vApp with SRM.

I.e., the Symapi Server on the SE vAPP is configured to allow secure connections only, therefor you have to add the user/host with the SRA's to the netcnfg file.

As I said, the configuration is a bit tricky, therfore I would also recommend to open a SR at EMC.

Regards,

Ralf

Good point Cody,  for the sake of clarity 

I am using EMCSRDFSRA_5.0.1.0  with the 7.5 SE (32bit) and the 7.5 vApp running SYMAPI

[codyhosterman]

Ah great thanks I just wanted to make sure, to save you a lot of troubleshooting effort in case it was the 5.1 SRA.

If you can post the EmcSrdfSra log here I would be happy to look at it, otherwise (and probably in addition) I agree with Ralf that you should probably open an SR.

[codyhosterman]

The error was:

Failed connection to SYMAPI server (192.168.160.127:2707). Error = The trusted host file disallowed a client server connection.

This error is due to the nethost file not being configured on the vApp. This can be resolved by logging onto the web interface of the vApp (https://hostname:5480) and adding in both the protected and recovery side servers FQDN or IP address with the user account that runs the SRM service. Alternatively an asterisk can be entered in for the user to allow all users from that host.

[MikeErter]

We have a call open with EMC, I'll post the fix when we have it.

I was able to add the Array Managers for the DMXs

I was then able to enable the array pair w/o errors

What needed to be done in our environement was to install and configure Solutions Enable (SE) on the SRM servers themselves, then start (and set to autostart) a few SYMAPI deamons.

The commands I ran on both SRM servers were:

stordaemon install storapid –autostart

stordaemon install storsrvd –autostart

stordaemon install storrdfd –autostart

stordaemon start storsrvd

stordaemon start storrdfd

run stordaemon list to check that the three daemons are running. The output should look like:

[*] storapid              EMC Solutions Enabler Base Daemon

    storgnsd              EMC Solutions Enabler GNS Daemon

[*] storrdfd              EMC Solutions Enabler RDF Daemon

    storevntd             EMC Solutions Enabler Event Daemon

    storsrmd              EMC Solutions Enabler SRM Daemon

    storstpd              EMC Solutions Enabler STP Daemon

[*] storsrvd              EMC Solutions Enabler SYMAPI Server Daemon

We have just added a new Knowledgebase article: Adding EMC SRDF Adapter fails when trying to add the Array Manager (2041557)

Hopefully this captures everything pertinent to this issue.

Thanks Rick,  it was only a week late for me LOL

Hi Mike,

Glad to know that the issue got resolved. However I wanted to know the configuration before when you hit the problem. i.e. whether the Solutions Enable(SE) was on a remote server other than SRM. I wanted to make sure that the KB Article which is written captures the scenario when the issue occurred. Also was the recommendation to install and configure SE on SRM Servers given by EMC?

Regards,

Amit

Hello All,

We are configuring SRM 6.o for the first time. We also facing the same issue and followed above steps given in KB article but still facing issue in adding Array manager.

Error : SRA command "discoverArray failed".

Also nothing is visible in EmcSrdSra logs

Request to help here urgently.
