STORAGE PROVISIONING - Detailed Steps

1). Creating STD device

Verify the Symmetrix status

symconfigure –sid 1234 verify

If any hung activities found abort

symconfigure –sid 1234 abort

Verify the available free space

symconfigure -sid SymmID [-v | -freespace [-units cylinders | MB]] list

or

symdisk –sid 1234 list  –disk_group 2

Create Command file

create dev count=8, size=12394, data_member_count=3, emulation=FBA,  config=RAID-5, disk_group=2;

Verify the command line syntax by performing PREVIEW using Symconfigure command

symconfigure –sid 1234 –f Create_hypers.txt –v –noprompt preview

Verify the Array readiness by performing PREPARE using Symconfigure command

symconfigure –sid 1234 –f Create_hypers.txt –v –noprompt prepare

Execute COMMIT using Symconfigure command

symconfigure –sid 1234 –f Create_hypers.txt –v –noprompt commit

Verify the newly created devices

symdev –sid 1234 list –noport

2). Forming Meta Device 

Verify the Symmetrix status

symconfigure –sid 1234 verify

If any hung activities found abort

symconfigure –sid 1234 abort

Create Command file

form meta from dev 26CA, config=striped, stripe_size=1920;

add dev 26CB:26E4 to meta 26ca;

Verify the command line syntax by performing PREVIEW using Symconfigure command

symconfigure –sid 1234 –f meta.txt –v –noprompt preview

Verify the Array readiness by performing PREPARE using Symconfigure command

symconfigure –sid 1234 –f meta.txt –v –noprompt prepare

Execute COMMIT using Symconfigure command

symconfigure –sid 1234 –f meta.txt –v –noprompt commit

Verify the newly created Meta devices

symdev –sid 1234 list –noport

3). Mapping

Find the host connected Director and Port details

symcfg –sid 1234 list –connections

Find the available addresses on that port

symcfg –sid 1234 list –address –available –dir 7d –p 0

Create a command file for mapping

map dev 26ca to dir 7d:0, lun=036;

Verify the command line syntax by performing PREVIEW using Symconfigure command

symconfigure –sid 1234 –f create_hypers.txt –v –nop preview

Verify the Array readiness by performing PREPARE using Symconfigure command

symconfigure –sid 1234 –f create_hypers.txt –v –nop prepare

Execute COMMIT using Symconfigure command

symconfigure –sid 1234 –f create_hypers.txt –v –nop commit

Check the device have been mapped

symcfg –sid 1234 list –address –available –dir 7d –p 0

4). Masking

Masking devices to the host

symmaskdb –sid 1234 –wwn 10000000c93f62cf –dir 7d –p 0 add devs  26ca –nop

symmask –sid 1234 –refresh

Check whether devices have masked

symmaskdb -sid 1234 list database -dir 7d -p 0
