VMAX 40K - Removing noport devices
Hi,
I noticed on the VMAX 40K there are over 700 devices that are listed in the -noport. Shouldn't the majority of devices be removed since they are in Not_Ready state, Not bounded to a Pool, and Not connected to an FA? Is there a best practices to keep a certain number of these devices?
Is there a simpler way to clean this up and do I have to balance the pools once the devices have been reclaimed?
Thanks,

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,
