CentOS LSI Raid card timeout constantly going into read only
This can be caused by PCIE Power Management
to disable PCIE Active-State Power Management First check the current policy using cat /sys/module/pcie_aspm/parameters/policy you should see something like default [powersave] performance vi /etc/grub.conf add this to end of the kernel parameters: pcie_aspm=off vi /etc/rc.d/rc.local add this to end: echo performance > /sys/module/pcie_aspm/parameters/policy reboot then test with: cat /sys/module/pcie_aspm/parameters/policy should show: default [performance] powersave |
