很多人說看不懂的部落格: iSCSI

最近有越來越多經濟實惠的iSCSI SAN儲存設備可以選擇, 剛好有些ProLiant內建的Multifunction網卡可以支援boot from iSCSI, 本文就來示範如何boot from iSCSI SAN.

需要設備及軟體:

(iSCSI Initiator) HP ProLiant BL460c G1 (embedded NC373i Multifunction NICs)
(iSCSI Target) HP LeftHand P4000 Virtual SAN Appliance Software
Microsoft Windows Server 2008 R2 x64 (下載試用版)
HP Gigabit Server Adapter Firmware Upgrade Utility for C-Class Blades
HP NC-Series Broadcom iSCSI Boot Package for Windows
HP Firmware Maintenance CD v8.60
WinImage

相關的設定值:

Initiator Name (BL460c): iqn.1991-05.com.microsoft:bl460c
Initiator IP (BL460c): 192.168.1.100
Initiator Route: 192.168.1.1
Target IP (LeftJand VSA): 192.168.1.101

建立iSCSI LUN並且present給server(BL460c):

在LeftHand CMC裡新增一台Server, 填入Name和Initiator Node Name, 並且把Enable load balancing選項的勾拿掉

在LeftHand CMC裡create一個iSCSI LUN(Windows Server 2008 R2 x64至少需要32GB), assign給剛剛create的server, 並記下iSCSI Target Name供後面設定使用

安裝並更新iSCSI Option ROM:

到http://www.bootdisk.com --> DOS/Windows9X/Me/NT/2K/XP Excellent Bootdisks 下載 "Windows Me OEM (bootme.exe)"

用7-zip之類的解壓縮工具把 "HP Gigabit Server Adapter Firmware Upgrade Utility for C-Class Blades" 解到一個資料夾

用WinImage打開bootme.exe, 把io.sys, msdos.sys, command.com以外的檔案都刪除. 然後加入ccfwupg1底下所有的檔案, 另存新檔為FW.IMA

把FW.IMA mount到BL460c iLO2的Virtual Flpooy並開機, 進入DOS後執行ccfwupg1, 完成後umount Virtual Floppy並關機

把HP Firmware Maintenance CD v8.60 mount到BL460c iLO2的Virtual Media並開機, 把所有的firmware都更新到最新版, 完成後umount Virtual Media並關機

設定並啟用iSCSI boot:

用7-zip之類的解壓縮工具把 "HP NC-Series Broadcom iSCSI Boot Package for Windows" 解到一個資料夾, 根據前面記下的設定編輯apps\bcm_iscsi\nc37x\tools\EVINPUT.TXT
