comment EMC VNXe GNU Source Code
This is a Q&A site for professional systems administration, and hacking and voiding the warranty of an expensive storage machine is not something that a professional systems administrator does.

Pretty sure that would void the warranty. If you don't like the way the storage is supported (and believe me, I get it- I'm curb stomping all my EMC at the first available opportunity), you make noise or just deal with the difficulty. You don't start logging in with an account that's only available to EMC employees.

And what would you do with the service shell that you can't do with an administrative user account?

messner, if I remember correctly, is the password for engineering mode in the clariion. That doesn't sound like what you're looking for, though...

What temporary password system is this? What would it allow you to do?

comment RAID-5: Two disks failed simultaneously?
Raid levels all have their use. Raid 10 throws half your capacity out the window, but doesn't make anything calculate parity. A good controller will calculate parity well enough that it isn't that slow, and will have a cache that hides the write penalty even more.

comment Can a NetApp disk array be used as a JBOD?
Could be both- disk for sure, but old FC cabinets will have some sort of ghetto switch that may also have been designed to avoid use this way.

@Wardy I think I misread your comment- absolutely, having your data in another set of disks in another chassis is better than local raid.

Whatever caused it to freeze his rebuild would still be in there, potentially. Sometimes bad sectors can't be recovered with a block copy. That said, to get this server back online, the professional solution is to recover from a recent backup and not spend time trying to do low-level data recovery which may not even work.

@Wardy, wouldn't raid 6 give you that?

I don't see the write penalty- random writes are cached, and sequential ones don't suffer as greatly from it.

comment Send interactive zoning commands to Brocade switch
Thanks :) I'm considering that program option, but it's a shame that Brocade makes this so hard.

comment Send interactive zoning commands to Brocade switch
I don't have screen installed on AIX... but reading about it, it certainly seems like something worth fighting to get. In the meantime, though, is there anything in the world of sessions, pipes, and redirection that can get me where I need to be?

comment Why would Linux VM in vSphere ESXi 5.5 show dramatically increased disk i/o latency?
I'm not sure, to be honest. I normally deal with it at a storage controller level, but this is on an internal disk.

You're welcome :)

comment Why would Linux VM in vSphere ESXi 5.5 show dramatically increased disk i/o latency?
Is there any chance this is due to ESX disk caching? Is the disk you're testing optimized for performance or safety? Also, if it's optimized for performance, can you look at the ESX cache utilization while you're testing? This write IO change in throughput looks like writes hitting a cache, and then slowing to the destage speed when it fills up.

I agree that while this is a well written question that presumably has a good answer, this isn't the place for it.

Stefan, if this is what ended up helping you, could you answer your question and accept it? That way future visitors with the same issue will see the answer more obviously :)

comment Where is $BASH_ENV usually set?
I just finished reinitializing SSH and my non-interactive SSH commands are now working! Thank you so much for your help, I'd have never found that field on my own.
