從 SAN 掛載磁碟 (RHEL 5.9)
儲存管理員告訴我,他從 SAN 將一個 3TB 驅動器放在我的伺服器上,並要求我安裝它。我知道的唯一資訊是它位於 LUN 1 上,並且磁碟為 3TB。
多路徑已設置,我已安裝 QLogic 驅動器。我不知道現在該怎麼辦……有這麼多磁碟我怎樣才能找到合適的掛載?我告訴儲存人員我在 SAN 上看到了所有內容,但我只是從他那裡得到“我不了解 Linux”。我不確定要問什麼問題才能確定要掛載的磁碟。
這是的輸出

不要使用
/dev/sd*
,因為它們僅映射到單個路徑。使用
/dev/mpath*
設備(或如 的輸出所示multipath -l
)。輸出
multipath -ll
顯示您要使用的磁碟是/dev/mapper/mpath1
在它上面創建你的文件系統,格式化它,分區它或者你喜歡的任何東西。只是不要使用這些

mpath1
代表到相同磁碟的單個路徑(多路徑通過查看 WWID 等來解決這個問題)。這意味著sd*
輸出中的所有磁碟都指向同一個設備,但使用不同的路徑到達它。這是出於冗餘,有時是出於性能原因。
