EMC VNX 5200 VIA initialization fails writing sysadmin password

We just initialized a new VNX 5200 and after finishing we couldn't log in with the new sysadmin password we choose. However we could log as root and nasadmin.

So we created a new global user  called temp from ssh connection to the CS and accessed unisphere with the new user and changed sysadmin password.

Below  you can see the command we used:

navicli -h spa security -adduser -user temp -password temp -scope 0 -role administrator

Finally we could enter Unisphere with sysadmin and finish the installation.

Error installing Exchange 2013 CU2 on Exchange 2007 organization

Yesterday I installed for first time a new Exchange 2013 on a company with Exchange 2007. We have installed some new 2013 Exchange but this was the first migration.

After accomplish all prerequisites on Microsoft guides we started to install and it ended on error.

The error was "length of the property is too long the maximum length is 64" and it was close to a line referring to Offline Address Book.

In Spanish the OAB was named "Libreta de direcciones sin conexión de exchange".

I googled a little and couldn't find any reference to this error and finally just tried something.

I just renamed the OAB to "OAB" and tried again to install.

This time installation finished OK!!!

EMC File Replication VNX to VNXe

Recently we needed to configure File replication from a VNX array to a VNXe.
I searched EMC support and communities and it was a surprise that there was no documentation or guide.

I have to look for the compatibility matrix again to see if it was possible.

Then I tried to do the inverse  one, VNXe to VNX as I had a manual.

https://www.ndm.net/emcvnx/pdf/vnx/h8270-replicating-vnxe-cifs-nfs-shared-folders-vnx.pdf

At first time I had a problem establishing the trust  and finally it result I needed to add a route at DataMover level on the VNX since the two arrays are in different subnets.

Once I got this solved I followed instructions and it worked fine. Also I tried to make a switch-over on replication and also worked.

Now I created a Replication Destination on Shared Folders screen of the VNXe. The wizard asked which one was the origin and created a Shared folder mounted as only read and with the right size and protection size.

When I tried to set a new replication from VNX as I entered the VNXe as destination the Unisphere screen failed.

I then tried to look for info about doing it on commands from Control Station and I found a blog where some one had the same problem. Thanks to Jon Austin by the way.

The main problem was how to know the destination FS ID on the vnxe system.

So I connected to ssh on both arrays.

On vnxe I logged as service and entered the service password which was the same that admin one.
I executed  svc_service_shell so I could use commands on the VNXe.
I don't know the password for that since some one form  support put it the day before for other thing and there is a time when it expires. It looks like it takes a couple of days until it expires.

Then I executed /nas/bin/nas_fs -list  so I could see the ID for the replication FS.

After I logged on  VNX CS with ssh as nasadmin user

I executed  nas_cel -interconnect -list so I could see the interconnect id (VNXe SPA)  where the destination FS was published.

and  finally executed this command and finally got replication started!!!

 nas_replicate -create FS_Name -source -fs id=13 -destination -fs id=42 -interconnect id=20004  -source_interface ip=x.x.x.x -destination_interface ip=x.x.x.x -max_time_out_of_sync 10 -overwrite

Overwrite option was needed because it fails other way.

That was all, after 20 hours file system is replicated and working fine.
