NetApp - Changing Gateway Settings

1. SSH to controller 1.
2. Type 'rdfile /etc/rc'
3. Copy the contents of the /etc/rc output to notepad. (Might want to save this to a file for safe keeping)
   1. Example
        1.hostname bob
           ifconfig e0a `hostname`-e0a mediatype auto flowcontrol full netmask 255.255.255.0 partner e0a
           ifconfig e0b `hostname`-e0b mediatype auto flowcontrol full partner e0b
           ifconfig e0c `hostname`-e0c mediatype auto flowcontrol full partner e0c
           route add default 1.1.1.1 1
           routed on
           options dns.domainname bob.local
           options dns.enable on
           options nis.enable off
           savecore
 
4. Change the notepad contents for the default route statement.
     1. Example
            1.hostname bob
           ifconfig e0a `hostname`-e0a mediatype auto flowcontrol full netmask 255.255.255.0 partner e0a
           ifconfig e0b `hostname`-e0b mediatype auto flowcontrol full partner e0b
           ifconfig e0c `hostname`-e0c mediatype auto flowcontrol full partner e0c
           route add default 2.2.2.2 1
           routed on
           options dns.domainname bob.local
           options dns.enable on
           options nis.enable off
           savecore
5. Make sure you get this right or your system won't boot. Copy the contents of the modified file to your clipboard.
6. In the SSH session type 'wrfile /etc/rc'
7. Paste the contents of your buffer into the SSH session.
8. Press Ctrl+C to quit the editor.
9. Verify, type 'rdfile /etc/rc' and make sure there are no extra line breaks or truncations.
10. Type 'route delete default'
11. Type 'route add default 2.2.2.2 1'
12. SSH to controller 2.
13. Repeat steps abvove

Netapp Snapvault : Transfer aborted: destination qtree is not coalesced

If you are working with NetApp SnapVault backups then at times  you'll experience one of the issue with "qtree is not coalesced". SnapVault update command will fail unless you poke the backup relationship with "Snapvault start " as below: (this will re-initiate the backup from its most recent checkpoint)

filer:/vol/source_vol/source_qtree dr_filer:/vol/dest_vol/dest_qtree Uninitialized - Idle with restart checkpoint (at 196 GB)


[root@cherrytop etc]# rsh dr_filer snapvault update dr_filer:/vol/dest_vol/dest_qtree 
 Transfer aborted: destination qtree is not coalesced.


[root@cherrytop etc]# rsh dr_filer snapvault start -S  filer:/vol/source_vol/source_qtree dr_filer:/vol/dest_vol/dest_qtree
Transfer started.
Monitor progress with 'snapvault status' or the snapmirror log.


filer:/vol/source_vol/source_qtree dr_filer:/vol/dest_vol/dest_qtree Uninitialized - Transferring (196 GB done)
