Hi toasters,
Is it possible to take a Solaris FC LUN and attach it to Linux via iSCSI? I suspect problems since the "lun create" command needs to know the OS type (solaris in this case). I don't think FC to iSCSI is a problem, though.
Naturally we would love to "just move" the LUNs without creating new Linux LUNs and copying the data from Solaris to Linux.
In case you are wondering about the FS on the LUNs, this is disk cache for a StorNext filesystem and we want to replace our very old Solaris hardware with Linux "in place". Otherwise it would take literally months to migrate the data since StorNext is a tape backed hierarchical FS.
If we can't do this hardware upgrade in place, then we will soldier on on the old Solaris hardware and cross our fingers.
We intend to replace StorNext eventually but want to get off the old Solaris hardware in the interim if possible.

I think the short answer is a LUN is a LUN and could be mapped to any igroup or collection of igroups you choose.
But the much longer answer is what does the maker of StorNext support? Sent via mobile.

Check out something called little and big "endian" (because plenty of sites can explain it better than me). Basically, Solaris and Linux have opposite endians, so mapping a lun with data written by Solaris to a Linux host just won't work as Linux can't understand the data. And yes, in my case where I had to migrate several business critical DBs from Solaris to Linux, it did take several months (in total, not per DB).

You always can map LUN. But I am not sure whether Linux will understand Solaris disk partition scheme. ________________________________________ From: toasters-bounces@teaparty.net [toasters-bounces@teaparty.net] On Behalf Of Steve Losen [scl@virginia.edu] Sent: Tuesday, October 11, 2011 02:06 To: toasters@teaparty.net Subject: Migrate Solaris FC LUN to Linux iSCSI ?
