[Networker] Byte order differences when moving from Solaris to Linux

Hi,

I know this has been discussed before, and I checked the archive, and Iread a lot of the posts -- some were mine! -- but I want to be clear onthis issue, and I don't think I am. It's been a while, and I know morepeople have migrated to Linux, so I wanted to clear this up.

We're considering moving from Solaris (NetWorker 6.1.1) to Red Hat Linux(NetWorker 7.2.1). Clearly, Solaris is Big Endian (okay, memory wise),and Linux is Intel X86 and thus Little Endian. Here are my questions:

1. The general consensus seems to be that the client indexes (6.x orlater) are endian neutral (they're stored in some format whereinNetWorker will not care about byte ordering) and will, therefore, not beaffected by this, *BUT* the media database is binary and could beaffected, true?

2. EMC Legato does not officially support moving from one OS to adifferent OS (even same endian), but people have done it successfully, true?

3. This should work as long as the transfer of the media database isdone in a manner wherein the data stream is endian neutral. For example,following the steps in the disaster recovery guide to back up theindexes and media database to tape (e.g. 'savegroup -o group -l full' onthe Solaris box and then 'mmrecov' on Linux end) and then recover toLinux end, (especially the media database). OR using 'uasm' to save theentire /nsr directory to a file on the Solaris end, transfer to Linuxend and then use 'uasm' again to extract from file, yes?

4. Is the media database in fact endian specific? I never could get ananswer from Legato on this. Does anyone actually know what exactly inNetWorker is endian affected? Is it just the media database? Maybe nothing?

5. How can we best test that the migration has worked and that there areno endian affected problems?


Thanks.

George
