Suse Ent 10 SP3 won't boot

hi I have Suse Ent 10 SP3 that when I reboot the server sometimes it won't... it behaves like this

up and running If I rebooted boots ok
so up and running again and If I rebooted again it won't from Hadr Drives

What I can check on my boot/grub?

why sometimes boots OK and sometimes does not

but the way I was thinking it was the HBA attached but I removed them

thanks a lot

reboot(2)							System Calls Manual							 reboot(2)

NAME
reboot - Reboots system or halts processor SYNOPSIS
#include <sys/reboot.h> void reboot( int howto ); PARAMETERS
Specifies a mask of options. DESCRIPTION
The reboot() function restarts the system. The startup is automatic and brings up /vmunix in the normal, nonmaintenance mode. The calling process must have superuser privilege to run this function successfully. However, a reboot is invoked automatically in the event of unre- coverable system failures. The following options, defined in the sys/reboot.h include file are passed to the new kernel or the new bootstrap and init programs. They are supplied as values to the howto parameter. The default, causing the system to reboot in its usual fashion. Dump kernel memory before rebooting; see the savecore command for more information. The processor is simply halted; no reboot takes place. The disks are not sync'd before the processor is halted or rebooted. Normally, the disks are sync'd (see the sync() command) before the processor is halted or rebooted. Because the disks are not sync'd with the RB_NOSYNC option, loss of data may result from using it. When no options are given (that is, RB_AUTOBOOT is used), the system is rebooted from file vmunix in the root file system of unit 0 (zero) of a disk chosen in a processor-specific way. (see the fsck command). RETURN VALUES
If successful, this call does not return. Otherwise, a -1 is returned and errno is set to indicate the error. ERRORS
If the reboot() function fails, errno may be set to the following value: The calling process does not have appropriate privilege. RELATED INFORMATION
Commands: crashdc(8), halt(8), init(8), reboot(8), savecore(8) delim off reboot(2)
