Hello macyero,

Here is a link to a KB that maybe of assistance. https://dell.to/34dWEkh

Thank you Sam

I forgot to mention that when you perform the following command:

[root ~]# symdev -sid [MY_SID] list -noport | wc -l

it shows over 600 devices. Listed below is how the most of the devices show up:

[root ~]# symdev -sid [MY_SID] list -noport

Symmetrix ID: 000000000000

Device Name Dir Device
---------------------------- ------- -------------------------------------
Cap
Sym Physical SA Config Attribute Sts (MB)
---------------------------- ------- -------------------------------------
009DF Not Visible ???:??? TDEV N/Grp'd NR 34530

...

Each device I would run the following to verify. Any METAs I dissolve: 

[root ~]# symdev -sid [MY_SID] show 009DF

[root ~]# symdev -sid [MY_SID] show 009DF | grep "Device Status"
Device Status : Not Ready (NR)

[root ~]# symdev -sid [MY_SID] show 009DF | grep "Meta Device Members"

[root ~]# symdev -sid [MY_SID] show 009DF | grep "Bound Pool Name"
Bound Pool Name : N/A

[root ~]# symdev -sid [MY_SID] show 009DF | grep "Front Director Paths"
Front Director Paths (0): N/A

With this array there are many devices that show they are set as Not_Ready (NR), Not bound to a pool or FA. Is there any reason to keep so many of these devices? Just checking if there is a best practices to keep for example 50 devices for future use.

Thanks,
