Buffer I/O error on devices error messages during booting OEL 6.7

rthampiJan 17 2018 — edited Jan 19 2018

Hi guys

We've installed OEL 6.7 on one of our TEST servers & during the booting were presented with hundreds of "Buffer I/O error on devices" & the minimum boot time exceeds more than 20 minutes due to these errors. We have a IBM DS3200 series storage system attached to this server using HBA interface (4G/s).

IBM storage manager doesn't report any issues with attached SAS devices, so we are not in a position to assess these read errors.

Please help us to troubleshoot this situation & fix these error messages causing extended delays in booting the system, Sample log as below

We are in the process of switching from RHEL to OEL for better Oracle supported environments & cannot recollected whether RHEL used to produce same errors prior the OS change.
