ESX3.5 SAN boot and multible storage groups error
I have 2 HP C-Class with 3 DL685c in each. They all have a mezzanine card that is interconnected to each Brocade SAN switch inside the C-Class. They have each a ISL port til my two main DS-24 McDATA switches. This gives me two fabric with dom id 1-2-3 on each. One B-switch is subordinated and one is Princepal. The active zone is sendt from the DS-24
I have made 6 different boot lun for all my ESX3.5 installations on the cx3_20, with navisphere agent and QLA BIOS enabled. All ESX hosts is allso registered in Navisphere Mgr and has it`s own NOVI0XBOOT storagegroupe that it is a member off.
All of them are stabile with no ESX3.5 installation errors.
Now I have made a large VMFS3 LUN and want to add all my registered navisphere ESX host to use it, but I get a warrning! It`s about that this host is a member of another storage groupe and if I make it a member of more than one storage groupe, the first storage groupe that it is a member of can fail or get unsable?? ( it`s boot lun ) I know that this is a issue in Windows Host...but this is VMware.
Have I forgotten to set any settings in Navisphere mgr?
Can I just say YES and the linux navisphere agent fixes it any way?
Anyone out there running a ESX3.5 boot LUN storage groupe and a VMFS storage groupe configuration?

Navisphere is telling you that a host can not exist in two separate storage groups. So what you can do is to add your LUN to multiple storage groups. When you right click on the storage group and click Select LUNs, find your new lun and drag it to the right. When you do the same thing for your next storage group in the pull down menu change "Not in other storage grups" to "All". Then find your Lun and drag it to the right. So when you are done all three hosts will see the same LUN and can do storage vmotion introduced in 3.5156

Thanks for the weekend response
This I know and I am sorry that I haven't explained my boot LUN problem correctly.
You`re way will be the correct way if all my ESX hosts have a local boot disk for the ESX installation. I am booting on the CX3_20 and all ESX hosts need to have it`s own didicated Storage group that only one ESX host is member. This is explained in a EMC technote; The QLA BIOS must not see several other ESX boot WWN LUN in its EMC storage groupe
But...Do you mean that I can add my VMFS3 LUN to the boot storgae group?

so when you done you will have these storage groups and luns:
ESXSERVER1 (boot_lun_ESXSERVER1, VMFSLUN1)
ESXSERVER2 (boot_lun_ESXSERVER2, VMFSLUN1)
ESXSERVER3 (boot_lun_ESXSERVER3, VMFSLUN1)
each storage group contains unique boot lun for that esx server plus the shared VMFS lun
take a look at document "EMC Host Connectivity Guide for VMWare ESX Server" located at
