LUN Expansion - TDEV

In The Below Example

<XXXX> - Symmetrix SID

0eb4 - Existing TDEV

Steps to expand a TDEV which is already provisioned:

• symconfigure -cmd "configure 1 devices copying dev 0eb4 overriding size=200GB;" commit -sid <xxxx> 

|| This will create a new device with same attributes as exiting TDEV. We’ll use this newly created TDEV to add to meta as member.

• Unbind tdev SymDevName[:SymDevName] from pool PoolName.

|| Or unbind the device from GUI. || Unbind the newly created device so that it can be added as member to the meta we are creating.

• symconfigure -sid 6404 -cmd "form meta from dev 0eb4, config=concatenated; add dev 112e to meta 0eb4;" preview –v

|| 0eb4 is provisioned TDEV and 112e is the new member being added to meta 0eb4.

• symconfigure -sid 6404 -cmd "form meta from dev 0eb4, config=concatenated; add dev 112e to meta 0eb4;" commit -v

Striping cannot be done for TDEVs which are already provisioned. They can be converted though later:
convert meta config=[, stripe_ size=[cyl]],[, protect_data=[TRUE | FALSE], bcv_meta_head=];
