Post subject:  3PAR 8200 show degraded disk
Hi,

I have an issue with my one of the PD that show that disk is degraded,
The weird thing is when I am checking from management console I see that on the same disk position there is another disk that the state of the disk is normal,
When I am looking in the front of 3PAR I can see that state of all 24 disks is normal (all of disks blinking with green light).
In total I have 24 PD FC over 2 cages.
I would like to know what I am missing?
Do I have really disk fault and replace the disk ASAP or its false alarm and how should I clear it?
Attached print screen from the system and output from CLI.

Looks to be like a disk replacement didn't fully complete servicemag

This is status without disk replacemnt,
Do I need replace the disk in any case?

Do showpd -i

I'm pretty sure there was a replacement at one point that didn't remove the old pd id on exit.

I can see that by AdmissionTime colum, disk ID 24 is different (newer) than others so I guess that someone before me replace the PD, how do I remove disk ID 23 (the degraded) from the system or there is another operation to remove PD that state is degraded?

I will run this command.
Last question, since I already ordered 1 PD FC same like that I have in the system, possible to add 1 PD without issues that may create unbalance of the system/RAID?
