Netapp smtape to external hard harddisk (workaround)

smtape is useful if you need to transfer huge volume over low bandwidth  network.  Let say i have a 7TB volumeA to transfer over to remote site , it is going to take forever to transfer.  smtape comes in as a solution, you can smtape to tapedrive and send the tape over to your remote site.

But what if your remote site does not have any tape library? I am going to show you the workaround smtape to volume(not tape drive) . smtape will create a single dump file and you can just copy it via CIFS/NFS to your external harddisk. Send it over to remote site, then attach the USB harddisk to one of Windows/Linux server, copy it into Netapp vis CIFS/NFS(temp volume) .

Steps
Source : VMware_ISO
Destination : test_restore
smtape temp volume : test_sm2t

Prerequisite : priv set diag

1. smtape backup /vol/VMware_ISO /vol/test_sm2t/dump/disk_file
2. vol restrict test_restore
3. smtape restore /vol/test_restore /vol/test_sm2t/dump/disk_file
4. snapmirror status

Snapmirror is on.

    Hi Sid,

    I will try my very best to help.

    1. What is the Ontap version running ? (source and destination filer)
    2. How did you copy the dump file? Any print screen for what you have done?

    Email me at cdestiny@gmail.com
