RAID5 Ready for rebuild?

[vinz_1]

I have exactlty the same problem. Have you found an explication and a solution?

This is typically caused by a problem with one of the other drives in the array.

The best way to find out which other drive it is is to check the array diagnostic utility and look for either one of the following: "Fl Rd Recv" or "Fl Wt Recv". These correspond to failed read recovery (unable to read the recovery info off of this drive) and failed write recovery (unable to write the recovery info to this drive).

An easier way will be to look for hard read or hard write errors in the system management homepage.

How I can deside this problem?
In Array Diagnostic Report (All Array Controllers):
Fl Rd Recv 0018 0004 0000 2102

What to do further?

hi

what you can do is upload the Array Diagnostic Utility report so we can help you to check which is the other HDDs that is causing that rebuild

hi

that error that Terry told you is related with every HDD so you will see that "Fl Rd Recv" a lot lot of times but that does not mean that all you hard drives are so What I found is this HDD has that error and needs to be replaced that means that HDD is not letting you continue with rebuild process
see attached picture

Errors please replace.
Port 1I, Box 1, Bay 1
Fl Rd Recv 001c
1c (Hex)-> 28 (Dec)

NO errors
Port 1I, Box 1, Bay 2
Fl Rd Recv 0000

something else backup your data because you need to recreate your RAID again unless you have RAID 6
I mean because one HDD failed and now another one needs to be replaced

The ADU shows:
Logical Drive status Ready for recovery.
Previous rebuild aborted due to read error.

HDD in Port 1L, Box 1, Bay 1 is bad and it have to be replace ; Fl Rd Recv count amount 28, this Fl Rd Recv will not allow any other drive to rebuild.

Fault Tolerance Mode Distributed Data Guard (RAID 5).
Logical Drive with 14 hdd's (including the failed hdd excluding the online spare)

Recommendations: make a data back up, re-create the array (remember to replace both failed hddâ s), activate the online spare (you have it but is not active) and load the data from back up.
Another recommendation is when you create the new array, select raid 6 (ADG) to increase fault tolerance

Remember that you have a raid 5; only one hdd can be down, if another hdd fails you may lost data.

Thanks to all.

I have same Question:

1. HDD in Port 1L, Box 1, Bay 1 is broken and I have a new HDD to re-create array?

2. If I have RAID5 with Hot Spare and two disk down data don`t lost?

hello

1. HDD in Port 1L, Box 1, Bay 1 is broken and I have a new HDD to re-create array?

2. If I have RAID5 with Hot Spare and two disk down data don`t lost?


so let response both with one answer
so insert the new HDD in that bay Port 1L, Box 1, Bay 1 if the rebuild continues your RAID is fine you dont have to backup and rebuild your RAID if you insert that new HDD is nothing happens that will mean recreate raid again.
you if you want insert new HDD and post the ADU report again
