Rescan devices on host

I know symmask/symconfigure commands for masking and mapping a device to a host.

Now my query is do I need to have the symcli installed on the host to which I am maksing the devices?

Can I unmask/mask devices using another host which is also connected to the same storage array.

I want run scripts from a central host and manage the storage provisioning.

in symmetrix world, masking is actually presenting devices to a host.

Yes you can..

Hi,

Are you removing or adding devices to host.

Unmask will remove the devices from Host HBA.

"I am trying to unmask(make device visible) to a host."

You can remove the devices using :

symmask -sid SymmID -wwn wwn -dir <#|all> -p <#|all> remove devs SymDevStart:SymDevEnd

For adding the device use:

symmask -sid xxx -wwn wwn -dir all -p all add devs SymDevStart:SymDevEnd

You would need to run: symmask refresh after each of the above commands.

Thanks

Ok. Got it Anoop, So I must be able to see the unmasked luns on the host right after the scsis bus rescan.

Ok, let me try this one.
