3Par drive showing degraded after servicemag was run

[Cloudcover]

There are 2pds on the same cage and mag. 1 is failed and the other one is degraded. 

Our tech run the servicemag that looks like the drive (pd102) has been replaced with the new pd 145. I think that caused the degraded status on the new replacement drive pd 145

I have very limited experience with 3par and the asset is no longer under contract with HPE

Not sure what to do at this point. Any help you can provide is very much appreciated

Hi Cloudcover,

The new pd (145) also showing missing from both loops. It looks failed; could be a faulty spare. 
Check the LED status of this PD. Try reseating it.
Once the PD becomes online good, the servicemag resume should kick in automatically.
After servicemag resume completes we can dismiss the old PDs

HI  veeyarvi 

Thank you for your advice and we were able to resolve our issue

But we have 1 more issue that i dont have any idea how to interpret and need your expertise pls

We have replaced pdid 29 and after running servicemag, status of 29 is showing degraded missing, not available for allocations (pls see attached pic pesan4.jpg)

From show alert i see an error "disk 5000C57DE6C31C failed (replace drive {0x46}, vacated {0x45}, invalid {0xa2}, inquiry failed {0xa3})" but could not find the disk 5000C57DE6C31C so not able to replace it (pls see attached pesan4 -3.jpg)

If you can pls point me in the direction of how to resolve this, I really very much appreciate

Thank you

Alfredo

Hi Alfredo,

Apologies for the delay. I am not sure the issue still persists.

could you share
showpd -s 29
servicemag status 11 2
showpd -failed -degraded

Hi Veeyarvi

We got it fixed, of course with your analysis and help

We just dismissed the degraded as there was already PDID for the same cage and mag

After dismissing, array is healthy with no degraded or failed drive

Again, thanks for your help
