EMC DMX-4 Storage Provisioning using CLI




STORAGE PROVISIONING - Summary

  • Creating STD device
  • Forming Meta Device
  • Mapping 
  • Masking 


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
