1. 關閉系統,進入PROM狀態 # init 0 ok (PROM狀態提示)
2. 在PROM狀態提示符下確認當前系統所連接的SCSI設備狀況 ok probe-scsi 或 ok probe-scsi-all
這時,系統將顯示所能識別的SCSI設備極其設備號(Target ID).如果新連接的硬 盤之信息沒有出現時,請按下述方法進行確認.
1) 檢查設備號是否重復? |
3. 重新起動系統 ok boot -r
注意,只有加入"-r"選項時, 系統在起動時才給所識別了的設備(包括SCSI設備) 生成相應的設備文件.
4. 對新增設的硬盤進行盤區劃分
進入系統狀態后,執行format命令,對新增設的硬盤進行盤區劃分.
執行例

(注1) 當改變其他分區尺寸時, 浮動區(Free Hog)用于在容量范圍內進行自動調 節.
(注2) 分區容量的具體指定方法為:
容量數值后面加"b": 指定塊數.
容量數值后面加"c": 指定柱面數.
容量數值后面加"mb": 指定MB數.
建議采用"mb",以兆字節為單位指定分區容量.
5. 生成新的文件系統用newfs命令將所劃分的分區生成為新的文件系統.
#/usr/sbin/newfs /dev/rdsk/c0t1d0s7 (CR)
如果在上述過程中將整個硬盤指定為一個分區,可執行下述命令.
# /usr/sbin/newfs /dev/rdsk/c0t1d0s2 (CR)
6. 檢查新生成的文件系統
用fsck命令檢查新生成的文件系統是否正確.
# /usr/sbin/fsck /dev/rdsk/c0t1d0s7 (CR)
如果在上述過程中將整個硬盤指定為一個分區,可執行下述命令.
# /usr/sbin/fsck /dev/rdsk/c0t1d0s2 (CR)
7. 安裝新生成的文件系統
建立安裝用目錄后用mount命令進行安裝.
例如,要將第7分區之文件系統用于home1時,可執行下述命令.
# mkdir /home1 (CR) |
# df -k (CR) |
為在系統起動時自動安裝新設文件系統,修改/etc/vfstab文件.
# vi /etc/vfstab (CR) |
# sync;sync;reboot (CR) |
