Before going for the LUN Provisioning, have understand the Symmetrix Architecture 

Basically, LUN allocation will have 4 simple steps like below

1. Creating STD device
2. Meta device creation
3. Mapping
4. Masking

The step by step procedure for LUN Provisioning in Symmetrix DMX is as follows:

1. Open a text file to create STD devices, by using the command

Create dev count=7, size=10240, emulation=FBA, config=2-way-mir, disk_group=2;

Execute the text file using symconfigure command with preview, prepare and commit options.

Symconfigure -sid XXX -f "name of the text file" -v -noprompt preview

Symconfigure -sid XXX -f "name of the text file" -v -noprompt prepare

Symconfigure -sid XXX -f "name of the text file" -v -noprompt commit

Verify the newly created devices by using the command

Symdev -sid XXX list -noport

2. Open a text file to form metas and devices to the meta head.

Form meta from dev 27CA, config=striped,stripe_size=1920; add dev 27CB:27E4 to meata 27CA


Execute the text file using symconfigure command with preview, prepare and commit options.

Symconfigure -sid XXX -f "name of the text file" -v -noprompt preview

Symconfigure -sid XXX -f "name of the text file" -v -noprompt prepare

Symconfigure -sid XXX -f "name of the text file" -v -noprompt commit

Verify the newly created meta devices by using the command

Symdev -sid XXX list -noport

Find the host connected directors and port details by using the command

Symcfg -sid XXX list -connections

Find the available addresses on that port by using the command

Symcfg -sid XXX list -address -available -dir 6 d -p 1

3. Open a text file with the following entry to map the device to the FA port

Map dev 27CA to dir 6d:1, lun=023;

Execute the text file using symconfigure command with preview, prepare and commit options.

Symconfigure -sid XXX -f "name of the text file" -v -noprompt preview

Symconfigure -sid XXX -f "name of the text file" -v -noprompt prepare

Symconfigure -sid XXX -f "name of the text file" -v -noprompt commit

4. Mask the devices to the host HBA

Symmaskdb -sid XXX -wwn 1000000c94d35cd -dir 6 d -p 1 add devs 27CA -nop

Refresh the Sym configuration by using the command

Symmask -sid XXX -refresh
