  1. BOM check error
During create cluster I am running into a bom check error
—————————————-
FIRMWARE-Check UCSC-SAS-M5HD : Required: 00.00.00.29,00.00.00.32,00.00.00.35,00.00.00.50,00.00.00.58, Found: 09.00.00.06; Action Needed: Update the Controller Firmware to Required Version
—————————————-
Can you please update the firmware on these 4 nodes. I am trying to install 3.5.2e on it
Solution :
A . Update Firmware on FI
B. Disable the bom check
go to each ctl
then open file /bin/bom-check.sh
comment out gen_Version_check from above code
hba_fw_check()
{
        CTLR="$1"
        FW_VER="$2"
        TYPE="FIRMWARE"
        ACTION_MSG="Update the Controller Firmware to Required Version"

        KEY="storage.controllers.${CTLR}.fw_version"
# Comment the below one to get pass the error
        gen_version_check "$CTLR" "$TYPE" "$KEY" "$FW_VER" "$ACTION_MSG"
}

 

2. Find FI from the ESX 

If you dont know the FI – You can check it from ESX with below command :

smbiosDump | grep -C5 “OEM Strings”

[root@ucs1367:~] smbiosDump | grep -C5 “OEM Strings”

    Data 10: 04 00 00 00 00 00 00 00 00 00 00 00 00 00 03 01

    Data 20: 00 00 00 00

  Type 204 Record: #99

    Data 00: cc 1c 63 00 03 00 01 02 00 00 08 00 00 00 00 00

    Data 10: 00 00 00 00 00 00 00 00 00 00 00 00

  OEM Strings: #102

    Cisco

    $SPI:rack-unit-14

    $SPT:hx-nodes-m5

$SYS:eng-fi78

 

3. Check the network speed for the FI connected to ucs610

ssh admin@eng-fi13.eng.storvisor.com

pwd : admin

run: Connect nxos

Show interface eth x/x detail

 

To find the Eth for the server node you are looking for :

Find the Eth with respect to the serial Number or Can find it easy from FI

eng-fi94-B(nx-os)# show interface chassis-info
    Chassis    Chassis    Remote      Chassis                   Module

Or You can find from FI too

Once you get the Eth – You can find the speed under “Speed” column : 10GbE

eng-fi94-B(nx-os)# sh int eth 1/1 bri

--------------------------------------------------------------------------------

4. Installer fails with ESXI reachability check – Check if the VLAN is right. I used wrong VLAN : 210 , the right VLAN is 211 .Once i fixed it – it worked.

ESXi reachability check
IP address: 10.104.32.126at default port: 902 is not reachable.
