二.進行磁帶備份
根據磁帶類型，放入同類型磁帶
/opt/ignite/bin （這個是make_tape_recovery 所在的目錄）
make_tape_recovery -A v (默認磁帶 /dev/rmt/0mn，此備份爲常用備份方式)
注意：如果掃描出的磁盤是 /dev/rmt/0mn ，並且類型是HP，可以直接使用上述命令。
如果掃描出的磁盤是 /dev/rmt/2mn（或者其他），並且類型是HP，就需要指定路徑： make_tape_recovery -A v -a /dev/rmt/2mn
-A : 指定要備份整個Root disk / Volume Group
-v : 用於顯示備份過程的提示信息
-a:指定路徑
備份成功顯示信息如下：

三.磁帶恢復系統
把磁帶放入磁帶機，把安裝光盤放入光驅，
磁帶恢復系統，需要用到安裝光盤引導，到此步驟，選擇 Boot from CD/DVD,Recover from Tape,然後進行恢復
