VMAX virtual provisioning


Step: 1 Thin device creation

create dev count=8, size=1150, config=TDEV, emulation=FBA;

Place the following in a command file "device" and use the following syntax to commit

symconfigure -sid 1234 -file device commit -nop

Display above created thin device, you will find it in NR state until bound

symdev list -tdev -unbound -sid 1234;



Step: 2 Data device creation

create dev count=8, size=1150, config=2-Way-Mir, emulation=FBA, attribute=datadev;

Place the following in a command file "datadevice" and use the following syntax to commit

symconfigure -sid 1234 -file datadevice commit -nop

Display above created data device

symdev list -datadev

Step: 3 Thin pool creation

symconfigure -sid 1234 -cmd "create pool P1 type=thin;" commit -nop

Step: 4 Add data devices to pool

Data device should be enabled before being used

symconfigure -sid 1234 -cmd "add dev 1A1:1A5 to pool P1 type=thin, member_state=ENABLE;" commit -nop

Display thin pool

symcfg list -pool -thin -sid 1234
symcfg show -pool -thin -sid 1234

Step: 5 Bind thin devices to thin pool

symconfigure -sid 1234 -cmd "bind tdev 1A1:1A5 to pool P1;" commit -nop

Step: 6 Map and Mask can be done by adding these devices to a storage group
symaccess -sid 1234 -name SG -type storage add devs 1A1:1A5 ;

Done!

Step: 7 Oh wait! What if I want to pre-allocate space?

May be done during the binding step or afterwards, lets preallocate 200MB for first two TDEV's in pool

start allocate on tdev 1A1:1A2 start_cyl=0 size=200 MB;

Place the following in a command file "prealloc" and use the following syntax to commit

symconfigure -sid 1234 -f prealloc commit -op

Display detailed info of the above creation

symcfg show -pool P1 -thin -detail -sid 1234
