Data Migration from scsi enclosure to DS2120

[Leon Shen]

Hi All,

I plan implement a data migration which i never did before. The current environment is rp3410 connect with scsi enclosure 70G(2.5 removeable storage) by use usb2.0. Now the 70GB enclosure out of space. I bought a DS2120 with 146GB disk space. I would like transfer all the data from the 70GB enclosure to the DS2120. Is anyone did before this ? I have few questions like ask.

1. The file in the 70GB harddisk is flat file, if transfer to DS2120. would the server detect?
2. What is the transfer speed ? One end is USB2.0 and another is ultra160. can I know how long take to transfer the 70GB.

Regards
Leon

Are you sure the rp3410 server has a usb connector.

I have yet to see a USB connector on a 9000 server.

Possible methodologies:
* tape transfer
* network scp/rcp transfer

I can't predict the speed in this operation. I can't predict that it will even work.

Please post back how it turns out.

The usb ports in HP9000 can be used for only mouse and keyboard. I am not sure in your case. If you are using USB for storage, can you please post how you did this?

If the server can see both enclosures, then just copy the data - different methods are available, fbackup, or my favourite - vxdump. Basically, create a new mount point for the new storage, then copy the data:

vxdump -0 -f - -s 1000000 -b 16 /oldmount | (cd /newmount ; vxrestore rf -)&

To see how long, add a timex in front

timex vxdump -0 -f - -s 1000000 -b 16 /oldmount | (cd /newmount ; vxrestore rf -)&
