EMC VMAX Virtual Provisioning



Consider following examples:-

Symmetrix ID = 1234
Host Name = CORALHOST
Data Devices = 0A00:0A03
Thin Devices = 0A04:0A05
Thin Pool = THIN_SATA

1). Create a Thin Pool

create pool THIN_SATA type =thin;
 
2). Create DATA Devices

Create 4 x 2GB Raid-5, DATA Devices.

create dev count=4, config=RAID-5, data_member_count=3, attribute=datadev, emulation=FBA, size=2GB, disk_group=1;
 
3). Add DATA Devices to thin pool

0A00:0A03 are DATA devices created in the previous step.

add dev 0A00:0A03 to pool THIN_SATA type=thin member_state=ENABLE;
 
4). Create Thin Devices

Create 2 thin devices of size 4GB each.

create dev count=2, config=TDEV, emulation=FBA, size=4GB;
 
5). Bind Thin Devices to Thin pool

0A04:0A05 are Thin devices created in the previous step.

bind tdev 0A04:0A05 to pool THIN_SATA;
 
6). Create Storage Group with name CORALHOST_SG and add the newly created thin devices

symaccess -sid 1234 -type storage -name CORALHOST_SG create devs 0A04:0A05

Now you all set!!!

You can verify your allocations using following commands:-
 
symaccess -sid 1234 show CORALHOST_SG -type storage / symsg -sid 1234 show CORALHOST_SG
