List clones and snaps of storage group

Hi,

Yes, I understand the device group is unknown -- the process I gave you first copies the contents of the known storage group to a new device group, which you can then query. It is two commands that will show you the relationships you're looking for.

Thanks,

Hi,

Give this a shot... you can use the 'symsg -sid sg2dg ' command to copy the contents of an SG into a DG, and then run a 'symclone -g query -multi' on the DG to show the clone relationships.

Here's an example from a lab box:

apple# symsg -sid 0240 show sean_test

Dynamox: looking for workaround as cant perform the task on 200 devices

Sean: The disk group is unknown, we know only storage group.

symdev show on source device and grep out clone/snap device id

don't think there is a "pretty" way of getting that info without getting into parsing output from other commands:

symclone -sid 123 list

symsnap -sid 123 list

To elaborate on this a bit more...

You can't run symclone/symsnap queries against SGs (only DGs), but you can copy the contents of an SG to a DG using the symsg sg2dg command as outlined previously. And you don't need to have the clone/snap targets in the DG in order to query clone/snap relationships -- you only need the source devices. So all you have to do is copy the contents of your known SG to a DG (using symsg sg2dg), then run 'symclone/symsnap -g query -multi' to see all of the relationships -- including the device IDs of the clone & snap targets.

Thanks,

Will there be any pre-checks to validate before performing on Prod? I think we are only creating a logical container for the devices?

what do you want to validate ? You are creating a logical container, you are not moving any devices.
