SaveDevice in Symmetrix
Hi
1. How to find whether particular symdevice is a SaveDevice or not. Is there is any property which tells it is SaveDevice or not under Symdev list -v command.
I know that this command gives -> symsnap list -savedevs - lists all the save devices. But i want know in Symdev command which tells it is save devices.
2. How we can know whether the Save device is allocated or not. I want to know the list of allocated and unallocated Save devices in the symmertrix.
3. There can be some Save Devices whcih can be allocated to Device group. But Device group wont have any Standard devices allocated to it. Then we can say those devices as un-allocated?
4. How to list all the session ... I think it is symsnap list. Please correct me if i amy wrong.
5. If the savedevice is part of the devicegroup then it will not be listed in
symsnap list -savedevs. Since it is already allocated to teh Device group.

I know that this command gives -> symsnap list
-savedevs - lists all the save devices. But i want
know in Symdev command which tells it is save
devices.
symdev list -sid 123 -savedev

symdev list -sid 123 -savedev -nonpooled

symsnap list. Please correct me if i amy wrong.
you are correct, that will list all active sessions on the box
5. If the savedevice is part of the devicegroup then
it will not be listed in
symsnap list -savedevs. Since it is already
allocated to teh Device group.
it will still be listed even if it's a member of device group. Device group is a logical container, it will not prevent devices from being displayed.

Is there is any way we can tell whether it is a save device by listing all the devices in Symmetrix using symdev list -v. Because symdev list -v will list all the devices including save devices. I don't want to execute separate command to list it. I want to identify the save devices from list of all devices give by symdev list -v.
