[HDS] How to manual force restore PN & SN

~ Applicable situation: SVP restore server blade settings (EFI/BMC)~

step01. SSH SVP (Chassis Management Module)

step02. use maintenance account / password > ceconsl / cepasswd

step03. (restore original PM & SN ,need remember information)
# set blade fru data [blade-locate] -pm [Product-Model] sn [Serial Number]
(sample)
# set blade fru data 5 -pm GG-XXXXXXXXXXX-X -sn 978GG-XXXXXXXXXXX-X-X0000XXXX

step04. 查看第五刀FRU資訊
# show blade fru data 5

step05. 重啟BMC套用新的PM & SN
# bmc-reset blade 5 -h

step06.登入SVP或HCSM作Refresh blade / chassis查看資訊是否寫入正確

step07.重新載入LP License (副檔名.tsv) ; 前提機器需關機才能註冊
登入SVP > System > LP License > Register
(PS: 若還是有問題請再次檢查 PM & SN是否和原先資訊有無出入;

若正確那只能用放大絕 >
SVP use “ceconsl" account login >點擊Blade > (右邊) Action > Restore Server Blade Settings > “Choice FRU restore" ,再重啟BMC , 最後再重新註冊LP License)

[HDS] Compute Blade 500 ‘LPAR’ install RHEL6.7

*Pre-check*
1.what is ur CB500 blade mode ? e.g. CB 520H B3
2.what is ur wnat to install RHEL version ? e.g. RHEL 6.7 x86_64
3.use Physical or LPAR ?

*Pre-require*
CB500_520Hx3_Driver_Utility_for_RHEL6_v0670-01.iso // 後面 v0{xx}即代表該符合RHEL版本,若是符合RHEL 6.9會顯示 v0690-01.iso
CB500_hfc_drivers_cd_0429.iso ( need extract dd.iso )

*Notes*
1. CB 520X B1/B2 and CB 520H B3 can boot only on EFI.
2. CB 520H B3 @ CB500 chassis 需符合FW
> MM : 至少 A023
> LPAR Manager  至少 02-05

*Tips*
IP address of management module : 192.168.0.1 ; https://192.168.0.1
Factory default account / password : administrator / password
following LPAR configuration is recommended :
|-CPU : 2 or more
|-MEM: 2GB or Large
|-Disk: 40GB or Large capacity
|-NIC: 1 or more

*Installation RHEL 6.7*

step01.
extract CB500_hfc_drivers_cd_0429.iso (Fibre Channel driver) 裡頭 hfc_media\linux\x86_64\rhel6\cd_media放置各版本6.x hfc dd.iso ; 因我目標是RHEL6.7所以拷貝 2.6.32-573.el6裡頭dd.iso匯出
hfc-0429-dd.jpg

step02.
vKVM mount media ‘RHEL6.7 x86_64.iso’

step03.
一開始安裝畫面選擇第二項 “Install system with basic video driver" then press ‘Tab’ key

step04.
add ‘ dd blacklist=isci ‘ ,then press ‘b‘ boot in

step05.
The message, Do you have a driver disk? click  “Yes" ; 此時將原RHEL6.7 ISO unmount ,change 2.6.32-573.el6-dd.iso

step06.
choice media /sr0 , then click ‘OK’

step07.
The message “Do you wish to load any more driver disks ?" > clock “No" ;載入HBA driver後系統會自動umount dd.iso ,所以再手動掛入RHEL 6.7 ISO

step08.
HDD custom use LVM 或 traditional extended partition 都OK

step09.
自訂安裝項目什麼都可以裝,唯獨有二個千萬別裝 (PS: CB 520H B3環境)
~ System Management > System Management > Optional packages >
freeipmi-bmc-watchdog-x.x.x-x.xx.xx
~ Base System > Base > tboot-x.xxx.el6.x86_64.rpm

step10.
Finsih install , reboot

step11.
Boot menu , Press E key ; Delete “intel_iommu=on" and “amd_iommu=on" from the boot option,and press Enter.

step12.
enter OS , config boot menu
> vi /boot/efi/EFI/redhat/grub.conf
" intel_iommu=on" // delete
" amd_iommu=on" // delete
" nmi_watchdog=0 pci=noaer " add
" terminal –timeout=10 serial console " // add
" quiet rhgb " // delete from the kernel line
" nmi_watchdog=0 mce=0 pci=noaer no_timer_check console=ttyS1,115200 " // add the ending of the Kernel line
" vga=792 " // add ,LPAR Manager version 至少 01-60
" kernel /tboot.gz logging=vga,serial,memory " // comment out
Change the first “module" to “kernel" in the line starting with “module /initramfs"
Disable TCP checksum offload function
> ethtool -k eth{x} // 顯示目前網卡各功能狀態
> ethtool -K eth{x} rx off tx off

Do not use NetworkManager service
> service NetworkManager stop
> chkconfig NetworkManager off
> chkconfig | grep NetworkManager // 再次確認

Customizing /etc/sysctl.conf

== Validate the magic SysRq key to collect information when a problem
occurs. Edit or add the following line. ==
kernel.sysrq = 1

== Add a setting to induce kernel panic when NMI occurs, with which you can
quickly detect a failure in hardware and drivers ==
kernel.unknown_nmi_panic = 0
kernel.panic_on_unrecovered_nmi = 1
kernel.panic_on_io_nmi = 1

==  Add or edit the following line to set the console log level to 3. By changing
the level, you can avoid the console overload, which can result in
significant deterioration of applications or in Linux hang-up ==
kernel.printk = 3 4 1 7

[Storage] HDS HUS130 Failed to create the volume. alert “DMED270010…."

HUS130在建立新的volume時發生了告警錯誤訊息如下

Failed to create the volume.
DMED270010: The process cannot be performed because the capacity of DP pool is insufficient or over the depletion alert value
of DP pool consumed capacity alert. Please grow the capacity of DP pool or change the depletion alert value of DP pool consumed capacity alert,

and try again.

Solution :
**在HSNM2操作**

1.HUS130_xxxxxxxx > Groups > Volumes 
2.點擊DP pool裡頭 “000″二下進去 // HUS130_xxxxxxxx > Groups > Volumes > DP Pool-000
3.右上有個" Edit Pool Attribute “點進去
4.修改 DP Pool Consumed Capacity
    4-1. Early Alert Threshold:改為98

    4-2. Depletion Alert Threshold改為99

Done.YOY
