Hello   That sounds like a logical place to start. After the system completes POST it initializes firmware interfaces like the PERC. After that it starts the boot process. It sounds like the problem is with something in the RAID chain. I would suggest troubleshooting the HDDs, cabling, and PERC. If something has failed in the RAID chain then it is possible the data on the drives has been damaged. I would start by disconnecting the drives. I can't remember if the PERC 4 on the 2850 is cabled to the backplane or if it is a hardware connection through the system board. If it is cabled then I would recommend disconnecting the cables from the PERC to the backplane. If it is a hardware connection then pull the hard drives out of the backplane. If the issue persists then the problem is with the PERC or the slot on the system board the PERC is installed in. I would reseat the PERC and try again. If the issue is resolved by disconnecting the components then the problem could be with any component that was disconnnected. That could be a cable, the backplane, or any of the HDDs. Thanks
Good afternoon, folks. We've got a legacy system that's been giving us trouble today, and I'd like to get a second opinion on the matter. We have a PE 2850 that refuses to boot. It'll go through all the BIOS checks and then stop without error. I suspect the problem is with our PERC 4e/Di. After it initializes the SCSI controller and scans devices, it shows 2 Logical Drives and 0 Physical Drives found/handled by host adapter. (There are two logical drives -- two physical disks in RAID 1 to boot from and another array, possibly RAID 5?) If I go into the PERC/CERC BIOS Conf Utility, sometimes I'm able to navigate the menu to View/Add Configuration before the menu freezes. Sometimes it freezes at 'Spinning up Device at Channel-0 Target-05'. Sometimes it freezes immediately and I'm unable to navigate the menu at all. But I'm unable to view the configuration or make any real changes that won't delete my disk configuration. I don't know how to proceed from here or what further troubleshooting I'm able to do to narrow down the issue. Does anyone have any advice for troubleshooting this issue? I'm happy to provide whatever information more that I can, but I'm hindered by the lack of a DRAC on this server.
