Symptoms
說明
在匯入 iDRAC 使用者屬性並啟用「密碼雜湊值」功能後,iDRAC 可能會停止接受遠端 IPMI 命令。

Error: Unable to establish IPMI v2 / RMCP+ session
Device not present (No Response)
Dell EMC iDRAC 新增了透過 HASH 和 Salt 值配對匯入 iDRAC 使用者密碼的支援。此功能可在匯入 iDRAC 使用者帳戶時增加額外的安全層。有幾種常見的方法可用於匯出和匯入具有雜湊密碼的 iDRAC 使用者密碼,可能會導致此行為:
- 伺服器組態設定檔匯出/匯入 (選用)
- 使用 HASH 密碼建立 RACADM CLI iDRAC 使用者 (選用)
- 使用 HASH 密碼建立 Redfish CLI iDRAC 使用者 (選用)
- 更換系統主機板後的簡易還原功能 (選用)
Cause
Dell EMC iDRAC9 在產品初次推出時,即推出了可遮蔽明文使用者密碼的新功能。使用 iDRAC 使用者密碼的加鹽雜湊值時,需要 Dell OEM IPMITOOL 來剖析散列密碼值。
Resolution
解決方案
「密碼雜湊值」功能需要受支援的 Dell EMC IPMI 工具版本,才能正確處理加密的 HASH 密碼。如需 HASH 密碼加密的支援,請至少使用下列 BMC 工具集中隨附的 Dell EMC IPMITOOL 版本:
Windows | ipmitool version 1.8.14.dell47| Dell EMC OpenManage BMC Utility,v9.1.0Linux | ipmitool version 1.8.14.dell51| 適用於 Linux 的 Dell EMC iDRAC 工具,v9.3.0
Dell EMC 對 IPMItool 所做的變更已提交至開放原始碼社群。某些 Linux 版本可能會利用尚不支援此變更的較新版本 IPMItool。
復原:
如果 HASH 密碼意外套用至 iDRAC 使用者帳戶,使用明文覆寫使用者密碼可讓第三方 IPMI 工具重新連線。
