Before the kernel is upgraded, the system can start and use normally, and when the system kernel is upgraded, the system does not start normally, this may be caused by the incompatible hard drive. can nowthroughEnter the old systemFollowThe following steps step by step to troubleshoot the cause:
①, query hard disk control chip manufacturer and model#lspci-nn | grep "SAS"#lspci-nn | grep "SCSI"
such as: SAS [ + :0078]
②, view HDD control chip driver used by old kernel#uname-A #注: You can view the currently used kernel name
Cat/lib/modules/2.6.28-16-server/modules.pcimap #注: Where 2.6.28-16-server is the old kernel name

and search According to the filter results of ① [ + : 0078], you can see the hard drive chip driver name used by the old kernel . such as:Megaradi_sas
③, find the driver module driver for the drive control chip *.kobased on ② search results, find drive file driver for hard disk chip *.ko#lsmod | grep "Megaraid_sas"
Megaraid_sas 74148 6
Scsi_mod 141236 3 Sg,sd_mod,megaraid_sas

④, check whether the new kernel hard drive chip driver supports the current chip manufacturer and model#modinfo/lib/modules/2.6.33-88-server/kernel/drivers/scsi/megaraid/megaraid_sas.ko #注: Suppose the new kernel is2.6.33-88-server

if the displayed result contains the hard disk control chip manufacturer and signal [+: 0078], then the MoD supports the current drive, if not included, the new kernel hard disk chip control driver does not support the current driver, At this point you need to download the appropriate driver source to the new kernel to compile.
⑤, download the source code pathftp://ftp.redhat.org/redhat/linux/enterprise/6Server/en/os/SRPMS/
Add the source code to the kernel to compile the method to be continued!
