Pinned topic x240 node and boot time

‏2013-02-05T17:01:14Z |
I've a x240 node that needs really long (10 min) to get through the boot process and to the point where ESXi begins to boot.

Most of the time it's sitting at "Connecting Boot Devices and Adapters". I've already tried to load the default settings because I thought I changed something essential while playing with pxe boot.

I'm not able to get a normal boot time, an other node only needs 3 min. I've compared the bios settings but can't find any differences.

Any ideas?

    thats common for UEFI based IBM blades, what happens is the HBA's scan all of the fabric. It will speed up once you've got a LUN or two attached to the blade

      All of the 3 nodes have already LUNs attached, I don't see why only one of them should take 10min.

        are the BIOS settings identical? HBA bios settings?

        have you tried this?

            I tried different options and the only one that significantly changed the boot time was setting "Adapter EFI Disable" to yes in the System Settings -> Adapter and UEFI Drivers section. We don't plan to boot from SAN so it's safe to disable it. Still don't understand why it takes ages to boot with this enabled there are only 3 LUNs currently presented to the nodes.

    Unless you are booting from SAN, try disabling option ROM for your FC HBA's. You do not need this enabled (if not booting from SAN).
    Once the driver loads it will find your LUN's.

    The delay could be the HBA Scanning for LUN's.

      Disabling option ROM didn't change the boot time. At least the BIOS option I tries.

      The only thing that reduced the boot time from ~10 mins to 3 mins was "System Settings" -> "Adapter and UEFI Drivers" -> Qlogic Fibre Channel Driver 1/2-> Fibre Channel Driver Configuration Utility -> 4. Edit Boot Settings -> 2. Adapter EFI Disable [y] -> 0. Previous Menu -> 11. Write -> 12. Quit

    Maybe related..

    When we were setting up these new x240's (4) we had a few issues with Boot stalling @ Bios.....maybe our guys did not wait as long as you have to see it boot..
    The issue was related (in our case) to the Brocade 16Gb Fibre Adapters, once we updated all the firmware to the latest levels out issue was gone.

    For what its worth...

    (you have the 8Gb cards.....but..)
