Lost Serial Cable that came with the E Class

Hello all,
I have got a Promise VTrack E Class and extension J Class and an Xserve.
After updated the firmware of E Class from 3 to 4.2, the Vtrack is in maintenance mode. Article found on Promise KB website deals with this situation :
As this article say, http://kb.promise.com/KnowledgebaseArticle10180.aspx?Keywords=rj11

Unfortunatly, we lost Serial Cable that came with the E Class to link Vtrack to XServe serial port. I Think it is really simple to homemade but I didn't find the schema on the web. It is a simple serial cable (RJ11 to DB9). Could someone help me to homemade it or find another way to exit maintenance mode.

Thanks a lot for your help
Chris

Manage Mount Volumes in Xsan 4

Hello everybody.
I have a question, maybe it's simple.

I actually have an Xsan 4 with a first Volume 1 created and regularly mounted on all my 8x clients connected.

Now i have to add a second volume with a new array, but some clients will have to mount only the first, some clients only the second, and some clients both volumes.

Now that the Xsan Admin is gone, how can i manage the mount of multiple volumes using the new profiler system?

Thank you very much for your time

remove open directory from MDC

I'm upgrading my xSAN to mountain lion from 10.6.8. I'd like to stop using OpenDirectory on my controllers. I have my clients connected to my "real" open directory server and everything seems to work ok except I have warnings in xsan admin showing incorrect search policy. If I demote the mdc replica to standalone, xsan admin complains that it is not a replica. When I demote the mdc master to standalone OD, or connected to a OD, xSAN admin says it should be a OD master.

Is it possible to undue the original configuration to use OD? Or should I just leave it as configured and ignore the warnings?

Xsan 4 & TimeMachine incremental backup problem

Hi All ,

I've been trying to backup a Xsan 4 Volume (10.10.2) on promise vtrak E610F with no luck .
once I've been trying host the Time Machine backup drive on OS X Server 10.0.2 and use it on one of the Xsans' clients .
every time the backup finishes , the client is trying to backup the all Xsan volume again and no incremental with an error message "Backup volume is out of space , find another place to backup to... "
alternatively , I've tried to connect the backup Volume and run the backup direct from there ,
but again it's not backup it incrementally , and running out of space after it's first backup .
am I missing something about xsan4 compatibility ?

Kind Regards ,
Pr0d

backup

hi all,

I have roughly 100TB on xsan, and would like to backup this data onto another san. I'm wondering if there are software out there that does good compression with video files. Allocating another 100TB would be so costly, son wondering how does every backup their data.

thank you
