scripted export VLUNs (createvlun)

[3padm]

Hi,

We have a 3par 7400 and plan to add additional esxi hosts to the fabric which all require to have the same vluns and lun IDs as the existing servers in the environment. Is there a way to genarate a cli command to grab the host to vlun relationship then export this info to the new hosts again using cli?

I realise this can be done with host sets but we cannot use this as Vmware SRM does not like them.

Thanks

See the "showvlun -host <hostname>" command in the HP 3PAR CLI Reference Manual.

There are a number of options for the commands listed in the HP 3PAR CLI Administrator's Guide to format the output in a script-friendly fashion. For example, "-csvtable" to output in comma-separated format rather than human-friendly tables.

Hi,

That is exactly what im looking for! Having looked at the reference doc, I cannot find the commands to export the vluns to new host, woudl this be using setvv by any chance.

Here is an output from your command

Lun VVName        HostName                     -Host_WWN/iSCSI_Name- Port Type
  0 VLUN1         esx-003 ----------------       --- host
  1 VLUN2         esx-003 ----------------       --- host
  2 VLUN3         esx-003 ----------------       --- host
  3 VLUN4         esx-003 ----------------       --- host
  4 VLUN5         esx-003 ----------------       --- host

what would the syntax be to say export these VLUNS to esx-010 ? And would it be safe to run the commands one after another or would you do one, check host in Vcenter and move onto next?

Thanks!

Assign them all and scan once. Read the Concepts, Admin guide, and CLI reference.

createvlun -f VLUN1 0 esx-010

If they are all in order like that, you can export them in one go by creating a VV set:

createvvset esx_vvset VLUN1 VLUN2 VLUN3 VLUN4 VLUN5

createvlun -f set:esx_vvset 0 esx-010
