We're in the middle of migrating from CELERRA to ISILON and are running into issues using both ROBOCOPY and EMCOPY.
In order to use these tools the initiatior needs to have sufficient rights on the source volume/share as these tools are file based.
In our organization the NAS administrator is not always the same person as the administrator of the shares and volumes and as such we don't always have the necessary rights on these volumes to read all files with skipped files as a result.
ISILON has a toold called "isi_vol_copy" which does block based copies using the NDMP framework .. however all documentation speaks about migrations between NetApp and ISILON. I'm now wondering whether this tool is also supported on CELERRA. Does anybody has any experience with this?
The NDMP data format is not part of the standard – its vendor specific
Isi_vol_copy was specifically written to “translate” between the NetApp and the Isilon NDMP data format
Emcopy should be able to cope with insufficient rights on the source files/dirs IF if is run as Domain Administrator with Backup privileges and the proper options.
Check the forum here – there were a number of posts about it
BTW there is also an Isilon support forum here at ECN
What you can do is run your process as a domain administrator. If you have more than one CIFS server on the celerra (ie it's in more than one AD domain) you may need to use a domain administrator for each server. It should get you most everything you need doing it that way.
Also, I have some tools i've written on my blog which may help you our a bit as part of the migration. I have a script to export your celerra filesystems and create the folder and quota on isilon, create your nfs and cifs shares, and one which will generate your emcopy commands for you.
Interesting - never thought about that. I think i'd just use nfs to copy the permissions and make sure to maintain the ACLs... I like to use cpio for these types of copies
If you use NFS to copy the data off of Celerra, you will lose the Windows extended ACLs, as NFS does not support these. You will need to use a copy tool like EMCOPY in order to retain all of the extended ACLs on each of the files in Celerra.
Don't forget about the other tools that go along with EMCOPY, like LGDUP and EMCACL, which can also help you retain ACLs and permissions as you copy.
lgdup mentions that source and target should be netbios name ..is that what you mean by "mapped drive" ? If that's the case, what do i specify for Isilon: SmartConnect Name, Cluster netbios name ?
You're probably right, I'm not sure I have the right privs to test it in the lab, so I don't know whether or not you can modify Isilon LGs from the command line. If you can only do so from the Admin console, then lgdup won't work.
