ESXi主機的多重路徑驗證

PDF

在「Foreign LUN Import（FLI）（外部LUN匯入（FLI）））」程序中、您應該確認主機上的多重路徑已設定且正常運作。

針對ESXi主機完成下列步驟。

步驟

使用VMware vSphere Client判斷ESXi和虛擬機器。
使用vSphere Client判斷要移轉的SAN LUN。

確定要移轉的VMFS和RDM（vfat）磁碟區：「esxcli儲存檔案系統清單」

如果VMFS具有extends（跨距VMFS）、則應移轉屬於跨距的所有LUN。若要顯示GUI中的所有擴充功能、請移至「組態」→「硬體」→「儲存設備」、然後按一下「資料存放區」以選取「內容」連結。

移轉後、將其新增回儲存設備時、您會看到多個具有相同VMFS標籤的LUN項目。在此案例中、您應要求客戶僅選取標示為標頭的項目。

確定要移轉的LUN和大小：「esxcfg-scsidevs -c」

識別要移轉的原始裝置對應（RDM）LUN。

尋找RDM裝置：「尋找/vmfs/volumes -name **-rdm**」

/vmfs/volumes/53843dea-5449e4f7-88e0-00262d04d700/Windows2003/Windows2003_1-rdmp.vmdk
/vmfs/volumes/53843dea-5449e4f7-88e0-00262d04d700/Windows2003/Windows2003_2-rdm.vmdk

/vmfs/volumes/53843dea-5449e4f7-88e0-00262d04d700/Solaris10/Solaris10_1-rdmp.vmdk

從先前的輸出中移除-rdmp和-RDM、然後執行vmkfsools命令來尋找VML對應和RDM類型。

PassthThrough為RDM、實體為（RDMP）、而非PassthThrough則為RDM、虛擬為（RDMV\）。虛擬RDM和VM Snapshot複本的VM會在移轉後中斷、因為VM Snapshot delta vmDK指向具有過時naa ID的RDM。因此在移轉之前、請客戶移除此類VM中的所有Snapshot複本。在VM上按一下滑鼠右鍵、然後按一下Snapshot（快照）→ Snapshot Manager Delete All（全部刪除）按鈕。請參閱NetApp知識庫3013935、以瞭解有關NetApp儲存設備上VMware硬體加速鎖定的詳細資訊。

識別LUN naa與RDM裝置對應。

判斷RDM裝置、虛擬機器對應及相容模式。

使用上述資訊、記下RDM對應至裝置、虛擬機器、相容模式和順序。

稍後將RDM裝置新增至VM時、您將需要此資訊。

確定多重路徑組態。
在vSphere Client中取得儲存設備的多重路徑設定：
1. 在vSphere Client中選取ESX或ESXi主機、然後按一下「組態」索引標籤。
2. 按一下「儲存設備」。
3. 選取資料存放區或對應的LUN。
4. 按一下*「內容」*。
5. 在「內容」對話方塊中、視需要選取所需的範圍。
6. 按一下*「Extent Device」（範圍裝置）>*「Manage Paths」（管理路徑）*、然後在「Manage Path」（管理路徑）對話方塊中取得路徑

從ESXi主機命令列取得LUN多重路徑資訊：

登入ESXi主機主控台。

執行esxcli儲存設備NMP裝置清單以取得多重路徑資訊。
