A couple of weeks ago, I posted about my issues with replication of >2TB LUNs on IBM SANs not working correctly using Enhanced Remote Mirroring. Well, IBM got me to install some hotfix firmware (version 07.60.40.00), and the problem appears to be resolved, though I’m still having issues with Flash Copies of one of the affected mirror LUNs showing up to Windows as an empty, uninitialized disk. I’m getting married in a week and am too busy polishing documentation before I take 2 weeks off to open yet another case with IBM. C’est la vie.
They’re probably going to kill me for calling this “hotfix firmware,” since I was assured this firmware was GA but not uploaded to the website because of some release engineering red tape. (Whatever, guys, I can’t download it without calling you, so it’s a hotfix as far as I’m concerned.)
Anyway, if you’re having this issue or are planning on replicating large LUNs with IBM Enhanced Remote Mirroring, contact your IBM support engineers and request that they send you firmware >=07.60.40.00.
