Create EMC Symmetrix thin devices

This post shows the step how to create thin pool, add and remove components from the pool and how to delete thin pool. TDAT and TDEV devices must be removed from the pool before it can be deleted. Thin reclamation on storage level is also shown here.

Create Symmetrix thin devices
symcfg -sid 1234 list -datadev : list all TDAT devices
symcfg -sid 1234 list -tdev       : list all TDEV devices
symdev list -datadev -nonpooled -sid 1234 : Check which TDAT devices not in any thin pool
symconfigure -sid 1234 -cmd "create pool test type=thin;" commit -nop : create a thin pool
symconfigure -sid 1234 -cmd "add dev f3d::f43 to pool test type=thin, member_state=ENABLE;" commit  -nop : add TDAT to a thin pool
symcfg -sid 1234 list -pools -thin -mb : list all the thin pools
symcfg -sid 1234 show -pool test -thin -mb -detail -all  : show detail of "test" thin pool
symconfigure -sid 1234 -cmd "bind tdev f25:f28 to pool test;" commit -nop : bind TDEV to "test" thin pool
symmask -sid 1234 -dir 4a -p 0 -wwn $a add devs f25:f28 : present TDEV to DMX masking
symaccess -sid 1234 -name testing_sg -type storage add devs f25:f28 : present TDEV to VMAX storage group

Remove TDAT device in pool
symconfigure -sid 1234 -cmd "disable dev f3d:f3e in pool test, type=thin;" commit : disable TDAT
symconfigure -sid 1234 -cmd "remove dev f3d:f3e from pool test, type=thin;" commit -nop : remove TDAT

Unbind TDEV device in pool
symdev -sid 1234 not_ready -range f25:f28 : set TDEV device not ready
symconfigure -sid 1234 -cmd "unbind tdev f25:f28 from pool test;" commit -nop : remove TDEV from "test" pool

Rename thin pool
symconfigure -sid 1234 -cmd "rename pool test to test123 type = thin;" commit -nop; : rename thin pool

Delete thin pool
symconfigure -sid 1234 -cmd "delete pool test type=thin;" commit -nop : delete "test" thin pool

Thin Reclamation on Array level
symconfigure -sid 1234 -cmd "start free on tdev 68B:68E start_cyl=0 end_cyl=last_cyl type=reclaim;" commit -nop (to start reclaim)
symconfigure -sid 1234 -cmd "stop free on tdev 68B:68E type=reclaim;" commit -nop (to stop reclaim)
