Step by Step Procedure for storage provision in DMX-4

1. Creating STD device

·         Verify the Symmetrix status

                symconfigure –sid 4282 verify

·         If any hung activities found abort

               symconfigure –sid 4282 abort

·         

          Verify the available free space

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

                                                or

               symdisk –sid 4282 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 usingSymconfigure command

             Symconfigure –sid 4282 –f Create_hypers.txt –v –noprompt preview

·        

         Verify the Array readiness  by performing PREPARE usingSymconfigure command

             Symconfigure –sid 4282 –f Create_hypers.txt –v –noprompt prepare

·        

        Execute COMMIT using Symconfigure command

            Symconfigure –sid 4282 –f Create_hypers.txt –v –noprompt commit

·         

        Verify the newly created devices

           Symdev –sid 4282 list –noport

2. Forming Meta Device

• Verify the Symmetrix status

                        symconfigure –sid 4282 verify

• If any hung activities found abort

                        symconfigure –sid 4282 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 usingSymconfigure ommand

Symconfigure –sid 4282 –f meta.txt –v –noprompt preview

• Verify the Array readiness  by performing PREPARE usingSymconfigure command

Symconfigure –sid 4282 –f meta.txt –v –noprompt prepare

• Execute COMMIT using Symconfigure command

Symconfigure –sid 4282 –f meta.txt –v –noprompt commit

• Verify the newly created meta devices

Symdev –sid 4282 list –noport

3. Mappping

·         Find the host connected Director and Port details

symcfg –sid 4282 list –connections

• Find the available addresses on that port

symcfg –sid 4282 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 4282 –f create_hypers.txt –v –nop preview

• Verify the Array readiness  by performing PREPARE using Symconfigure command

symconfigure –sid 4282 –f create_hypers.txt –v –nop prepare

• Execute COMMIT using Symconfigure command

symconfigure –sid 4282 –f create_hypers.txt –v –nop commit

• Check the device have been mapped

symcfg –sid 4282 list –address –available –dir 7d –p 0

4. Mappping

• Masking devices to the host

symmaskdb –sid 4282 –wwn 10000000c93f62cf –dir 7d –p 0 add devs  26ca –nop Symmask –sid 4282 –refresh

• Check whether devices have masked

symmaskdb -sid 4282 list database -dir 7d -p 0
