How can we check the number of spindles on a particular symmetrix device ?

Question

I need to check the number of spindles on each symmetrix devices allocated to a host. How do we check this in ECC?

I guess the answer depends on what you mean by spindles, but the way I would interpret this would be that you want to find out for any given device, how many physical disks have hypers that make up that device.

While it is simple enough to say that a RAID 1 device is going to be on 2 spindles, and RAID 5 on 4 or 8 (depending on 3+1 or 7+1), it isn't as easy if you are talking about meta devices, so here is how I would check.

Change to Visual Storage view (the drop down by Storage Allocation and select from the list). Then select you device in the tree view on the left. If it is a Meta, make sure you expand it and select all the component devices as well.

In the Visual Storage view you will see a representation of where all the hypers are on the physical drives in the array.

BTW - I LOVE this view!

Hi,The Relationship view in the Console is your best bet. Just drag the physical device from the tree panel and it will show you all of the logical devices on that spindle.Regards,Séamus CoffeyEMC Global Services

Sorry Seamus, I misread your note and thought you were giving instructions to do something else (it's been a long day). Your method will do the same thing in a different format... which may be easier to work with for the uninitiated.

I still prefer the Visual Storage view for what it can do on a larger scale.
