Troubles with snapmirror: cannot connect to source filler

[raef_mansour]

Guys,

I’m having an issue and need some help. My destination filer cannot connect to the source for some reason and my snap mirror is failing.

Both are up on the network, pingable.

I m not familiar with the use of file like snapmirror conf or /etc/file thats why i used the storage manager to set the snap mirror relationship

on local i have DOT 7.3.3 on DR site I ave 7.3.6

i have set options snapmirror.access to all on both controller

options snapmirror.checkip.enable to on also

I have modified the etc/snapmirror.allow (adding all ip and name of other side storage machine)

rdfile /etc/snapmirror.allow

192.168.141.101

192.168.141.103

192.168.141.104

192.168.141.106

AFDB_NSERIES_HAUT

AFDB_NSERIES_BAS

AFDB_NSERIES_BAS-e0a

AFDB_NSERIES_BAS-e0b

I have tried a lot of syntax for snapmirror but always the same message: cannot connect to source filer...

snapmirror initialize -S 192.168.141.103:vol_test   AFDB_DR_NSERIES_BAS:vol_test_SnapMirror_21Jan2012_133245

snapmirror initialize -S AFDB_NSERIES_BAS-e0a:vol_test   AFDB_DR_NSERIES_BAS-e0a:vol_test_SnapMirror_21Jan2012_133245

snapmirror initialize -S AFDB_NSERIES_BAS:vol_test   AFDB_DR_NSERIES_BAS:vol_test_SnapMirror_21Jan2012_133245

I need your advises please

Hi

Please try and log onto the source filer ssh name of filer and type

options.snapmirror.access host=nameofdestserver1,nameofdestserver2

Make sure you have dns or wins setup and is resolvebale on source and dest other put some static entries in host files if you dont have it.

/etc/hosts

Hi Raef:

Also forgot to say make sure you have a valid snapmirror license on bothe boxes:

type

license

and check there us a code for snapmirror

This could be the culprit, also make sure that the snapmirror port number is allowed in the network.

Hope these tips help:

Do we need traceroute complete ?

So, what could be the problem ?

snapmirror license is there.

Please help.

Thanks and regards

Hi,

There are things that need to be consider.

-The gateway both source and destination is reachable.

-ip address and hostname is reachable.

-set options snapmirror.access all in both filers (source and destination)

-snapmirror license must be set in both filers (source and destination)

Then do this,

destination_filer>snapmirror initialize -S source_filer:volume1 destination_filer:volume2

      or

destination_filer>snapmirror initialize -S 10.10.10.10:volume1 destination_filer:volume2

use either hostname or ip address of source.

Hope this could help you.

Regards,

Arth

Had a similar issue some time back. In my case, it turned out to be a name resolution problem. Try to ping the destination filer from the source filer (and vice versa) using it's hostname and see if you get a response. You may find that while the IP is ping-able, the hostname is not, which may point to the absence of a DNS entry for your filers in your locally configured DNS server. If this is the case, create a DNS entry for both filers. A workaround could be to add an entry in /etc/hosts for the partner filer.
