[VMware] Cannot power-on VM ‘A general system error occurred: No connection could be made because the target machine actively refused it(發生一般系統錯誤:無法連線,因為目標電腦拒絕連線)

有人反應一台虛擬機器匯人後無法開機,會出現如下錯誤訊息

Solution:

~vCS~

services.msc > VMware vCenter workflow manager service > Start

~vCSA~
> service vmware-vpx-workflow restart

> shell.set –enabled true
> service-control –status vmware-vpx-workflow // check status
> service-control –start vmware-vpx-workflow

最後再試著Power-on VM , enjoy

[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)

[Lenovo] LXCA忘記本機帳號密碼 ?

客戶反應當時設定預設帳號 ‘ admin ‘忘記了密碼,因Lenovo XClarity Administrator後台Linux是沒有預設帳密所以無法由後台來重置密碼 .

Solution :
(sample account > admin )
在重置密碼前要確認原這帳號是否有歸屬lxc-recoverylxc-supervisor 角色群組。
** 建議在安裝後LXCA立即將該帳號歸屬lxc-recovery & lxc-supervisor group **

step01. Graceful shutdown LXCA VM

step02. 編輯個文檔檔名叫 " passwordreset.properties "
#vi /tmp/passwordreset.properties
——————-內容——————-
user=admin
password=PASSW0RD
——————-內容——————-

step03. 將該檔案’passwordreset.properties’作成ISO檔。
~Windows
可用像UltraISO或Imgburn製作

~Linux
# mkisofs -V passreset -J -o /tmp/passreset.iso /tmp/passwordreset.properties

step04. 上傳到ESXi datastore 或 Hyper-V Library

step05. 掛載passreset.iso

step06. 開機LXCA過程它會讀取這個檔案即可重置 admin這帳號密碼變為我們所設定"PASSW0RD"

step07. http://lxca-ip-address/ui/index.html 若登入沒問題即立即變更密碼唄!

step08. 退出passreset.iso

Done

[VERITAS] Backup Exec 15 到期備份集不會自動刪除?

客戶反應在升級Backup Exec 15前的備份集在"儲存"保留時間設定更短但就是不會自動刪除,
就請她檢查DLM (Data Lifecycle Management)的值"CheckReclaimSpaceIntervalMinutes“是否被停用(十進位:0) ,果真在之前曾被停用請她改回(十進位:60)即可正常的判別自動刪除到期的資料。

Solution:
step01. regedit.exe (以系統管理員身份執行)

step02.
HKey_Local_Machine\Software\Symantec\Backup Exec for Windows\Backup Exec\Server\
CheckReclaimSpaceIntervalMinutes
unnamed.png

step03.
啟用"CheckReclaimSpaceIntervalMinutes (十進位:60)" // 預設是啟用

step04.
Restart BE all service.

Done.
