Del BCV after extending striped meta ?

Hi,

Is there a faster way in Enginuity 5876 to delete a BCV+TDEV other than unbind, dissolve,..   after a TDEV extension ?


1) create bcv+tdev from TDEV to extend.  symconfigure -cmd "configure 1 devices copying dev 0588  overriding config=bcv+tdev;"

2) Alocate bcv+tdev. symconfigure -cmd "allocate tdev 05D1 start_cyl=0, end_cyl=last_cyl, allocate_type=persistent;"

3) create new tdevs to extend.  symconfigure -cmd "create dev count=1, config=TDEV, emulation=FBA, size=#### CYL;”

4) Re-Stripe data across tdevs using bcv volume. symconfigure -cmd "add dev ### to meta 0588, protect_data=TRUE, bcv_meta_head=####;”


4 steps to extend and 4 more to tear down the bcv volume. 


Thanks

There is not but if the meta you are expanding is a standard size in use in your environment you can simply unbind the BCV (which will deallocate all of its extents) and leave it in place for use again in the future.

You can use EMC Storage Integrator (ESI)'s PowerShell Cmdlets for Lun Extension (Get-EmcCompositeXXX, Exapnd-EMCLun etc. cmdlets) (to manage VMAX arrays, ESI uses SMI-S Provider)

Note: as you may have guessed, ESI supports selected few provisioning operations for VMAX, VNX and VNXe, and Lun Extension is one of them.

SymCLI (set of cmds) supports lot of features which ESI doesn't have - for ex, Auth and ACL support etc.

Regards.
