Step by Step Procedure for
Storage Reclamation
- Unmasking
- Unmasking devices from the host
symmaskdb –sid 4282 –www 10000000c93f62cf
–dir 7d –p 0 remove devs 26ca
- Refresh the Symmetrix Array
Symmask –sid 4282 –refresh
- Write Disable
- Write Disable the devices before unmapping from the Director and from port
symdev -sid 4282 write_disable
26ca -sa 7d -p 0 -noprompt
- Un-mapping
- Create a cmd/txt file with the following line
Unmap dev 26ca from dir all:all;
- Perform preview operation using symconfigure command
Symconfigure –sid 4282 –f
unmap.txt –v –nop preview
- Perform prepare operation using symconfigure command
Symconfigure –sid 4282 –f
unmap.txt –v –nop prepare
- Perform Commit operation using symconfigure command
Symconfigure –sid 4282 –f
unmap.txt –v –nop commit
- Verify that the device has been unmapped
Symdev –sid 4282 list -noport
- Dissolve meta
- To Dissolve meta create a cmd/txt file with the following line
Dissolve meta dev 26ca;
- Perform preview operation using symconfigure command
Symconfigure –sid 4282 –f
dissolve.txt –v –nop preview
- Perform prepare operation using symconfigure command
Symconfigure –sid 4282 –f
dissolve.txt –v –nop prepare
- Perform Commit operation using symconfigure command
Symconfigure –sid 4282 –f
dissolve.txt –v –nop commit
- Verify that the meta has been Dissoved.
Symdev –sid 4282 list –noport
- Deleting hypers
- To delete the hypers create a cmd/txt file with the following line.
Delete dev 26ca:26d1;
- Perform preview operation using symconfigure command
Symconfigure –sid 4282 –f
dissolve.txt –v –nop preview
- Perform prepare operation using symconfigure command
Symconfigure –sid 4282 –f dissolve.txt
–v –nop prepare
- Perform Commit operation using symconfigure command
Symconfigure –sid 4282 –f
dissolve.txt –v –nop commit
- Verify that Hypers have been deleted.
Symdev –sid 4282 list -noport
