Solaris/vxvm/EMC Lun configuration

Hello all,

i try to allocate the same LUN to two server (or more in the future)
i use solaris 10, vxvm (vxfs) for data and solaris zones and EMC DMX-4, i try to migrate solaris zones between servers in case of problem.

and this is what i want to do

  • affect LUN to srv00124 and srv10155
  • the LUN must be imported only on one server
  • in case of problem
    • export or forcing import LUN to the other server
    • mount all file system
    • migrate the solaris zone
  • roolback when the problem are resolved

anyone have suggestions ?
is this config file for making and mapping LUN are correct for affection on two server ?

Thanks a lot,

This is quite involved.

There is major documentation that exists on this which I have somewhere. What major documentation have you already got? Please detail.

If you don't have much I will find what I have and upload it but will need to acknowledge all necessary copyrights and check that moderators are okay with that.

Hello hicksd8,

My major documentations is just the white papers from Sun and some documentations regarding EMC storage

i haven't find a good documents for EMC staorage and vxvm for doing this solution.

i have an other idea for if i can't make this solution but it not professional and not good :mad:

the other solution is (i know it's stupid) :smiley:

  • halt and detach zone
  • umount fs
  • export dgs
  • romve mapping from the fist server
  • remapping on the second server
  • scan and export dgs
  • mount fs
  • attach zone

It will be good if you have good documents that you can share it.

thanks in advance

I just realised that I have already uploaded this document to Unix.com sometime ago here:

The document is EMC_SolarisHostConnectivity.pdf

I'm not answering your question directly but I hope this document helps. Let us all know if it does or doesn't.

We all acknowledge the copyright of EMC and its associates in this material.

Hicksd8 thanks a lot i think that the solution are on the cluster chapitres :wink:

i will post some informations when i resolve this issue

You are welcome. A huge lot of bedtime reading I think!!!

If you have unanswered questions despite the documentation do post back and I will try and help.

There's a lot to know. Quite a project. Good Luck with it.
