snapmirror error could not read from socket (error 13102)

[soper_2010]

Hi!

i have faced a problem with snappmirror.

we have 2 x fas2020 ontap 7.3.3, and snapmirror working fine in both directions

we have bought one FAS2240-2 and one Fas 2240-4 v.8.1.1.7 and snapmirror working fine in both directions

But when i set up a snapmirror from one fas2020 as source to a Fas2240-4 i got the error:

snapmirror error could not read from socket (error 13102)

snapmirror.src.sockErr     Access denied for SnapMirror/SnapVault destination.

i looked at the host files and se there are no missmatch.

the options look like:

san1 (FAS2020)	san2 (FAS2020)	san4 (FAS2240-4)
snapmirror.access            host=san2 snapmirror.checkip.enable    on snapmirror.delayed_acks.enable on snapmirror.enable            on snapmirror.log.enable        on snapmirror.readahead         0 snapmirror.readahead_freq    0 snapmirror.vbn_log_enable    off snapvalidator.version        9	snapmirror.access            host=san1 snapmirror.checkip.enable    on snapmirror.delayed_acks.enable on snapmirror.enable            on snapmirror.log.enable        on snapmirror.readahead         0 snapmirror.readahead_freq    0 snapmirror.vbn_log_enable    off snapvalidator.version        9	snapmirror.access            legacy (but if i set to lhost=san1 the result is the same) snapmirror.checkip.enable    off snapmirror.delayed_acks.enable on snapmirror.enable            on snapmirror.log.enable        on snapmirror.vbn_log_enable    off snapmirror.volume.local_nwk_bypass.enable on snapmirror.vsm.volread.smtape_enable on snapvalidator.version        9

san4> snapmirror status

Snapmirror is on.

Source                     Destination                      State          Lag        Status

san1:Test_for_cifs    san4:test_second_snap  Uninitialized  -          Idle

san1 have a snapmirror.allow file and it look like:

san2

10.10.10.20

................

san2 have no snapmirror.allow file

............

san4 have no snapmirror.allow file.

Anyone have any idea what can be wrong?

SAN4 needs to be in the snapmirror.allow file for SAN1.  Unless SAN4's IP is 10.10.10.20, then you will get the error your describe.

Thanks for answer!

now i put san4 to the snapmirror.allow file for SAN1 so it look as shown now! becouse i need both san2 and san4 to be able to sync the data with san1. the content of file was :

san2

10.10.10.20

and i put san4 int´a new line so it become:

san2

10.10.10.20

san4

10.10.10.44

and the result is the same, and get the same error.

Just to be certain, I don't think you want host names in your snapmirror.allow unless they are defined in your /etc/hosts.  Try this just to make sure:

SAN1 snapmirror.allow:

10.10.10.20  #  Assuming this is for SAN2

10.10.10.44  #  Assuming this is for SAN4

Another question:  Do you have any firewalls or routers between SAN1 and SAN4?  Can you verify something in the middle isn't stopping SM traffic between the two?

Thanks again!

I solved it, changed options snapmirror.access to  legacy and it solved the problem.

The host file was correct and the dest.filer were defined in  snapmirror.allow
