W2012: IO operation was retried
Hello
I have a DELL PE 2950 III and I read some errors in the Windows 2012 event logs:
The IO operation at logical block address 6bac027 for Disk 2 was retried.
The IO operation at logical block address 800 for Disk 3 was retried.
The IO operation at logical block address 800 for Disk 4 was retried.
These errors appear when I backup the virtual machines (Hyper-V) hosted on this server after I upgrade from Windows 2008 R2 to Windows 2012.
And from several years I have a predictive error for one disk:
Predictive Failure reported: Physical Disk 0:0:3 Controller 0, Connector 0
1) Should I change these SAS disks? The model is not easy to find in my country.
2) Should I update the firmware of all SAS disks?
3) Another idea?
The server configuration:
- Dell PowerEdge 2950 III.
- RAID controller: Perc 6/i (firmware 6.3.1-0003, A14)
- RAID 5: 6 x 146 GB ST9146802SS + 2 x 146 GB ST9146803SS.
- Disk ST9146802SS: original firmware (2 new versions exists)
- Disk ST9146803SS: original firmware (a new version exists)
Thank you

1) Should I change these SAS disks? The model is not easy to find in my country.
--Yes, i would replace the drive in predictive failure. It may run for awhile, but eventually it will fail and you don't want to risk your data.
2) Should I update the firmware of all SAS disks?
--Yes, it is a good idea to update the firmware on the drives. It helps with their interaction with the controller.
3) Another idea?
--Make sure your bios is current as well, at 2.7.0
Regards,
yourids

ok thank you, I will buy a new disk and update the other disks and the BIOS.
Could you give me the reference of a compatible disk from DELL?
I think I could even install a 300GB disk if the 146GB does not exist anymore.

I would suggest something similar to this:
You can always go larger on the drives.

The system event log is consistently showing the following error when backup is running:
"The IO operation at logical block address xx for disk x was retried." Source: disk. Event ID: 153.
We too are backing up VMs. The system is new with Server 2012 Standard. Dell PE R420. BIOS: 1.5.2. RAID 1 for OS and RAID 5 for data. HDD info:
146GB 15K RPM Serial-Attach SCSI 6Gbps 2.5in Hotplug Hard Drive (342-0427) - Quantity 2
300GB 15K RPM SA SCSI 6Gbps 2.5in Hotplug Hard Drive (342-2240) - Quantity 5
Do you have any recommendations for this scenario?
