［HP-UX］怎样增加一个硬盘？

hero03

我的服务器的空间已经满了，想增加一个硬盘，
由于是SCSI接口的，那这个硬盘的ID号怎么配？
如何扩充已经满的文件系统？

[B]1. Use ioscan -fnC disk to check your system config.

2. you may find some disks like :

    /dev/dsk/c?t?d?

  just keep your mind on those numbers behind letter \"d\", they are the scsi disk id, so choose your new SCSI disk id no conflict to your exist disks id.

3. shutdown server, install disk in your server.

4. Power on server, use ioscan -fnC disk to check your disk is already installed.

5. pvcreate /dev/rdsk/yourdisk(c?t?d?)

6. vgextend yourvgname younewpvname(/dev/dsk/c?t?d?)

7. if you have JFSonline, you may do

      fsadm -F vxfs -b yourfilesystemsize  /yourfilesystemmountpoint

8. Otherwise, you have to

      umount /yourfilesystemmountpoint(shutdown your application first)

9. lvextend -L yourlvsize /dev/yourvgname/yourlvname /dev/dsk/c?t?d?

10. if your file system is HFS,

       extendfs -F hfs /dev/yourvgname/ryourlvname

    or if your file system is JFS

       extendfs -F vxfs /dev/yourvgname/ryourlvname

11. mount your file system back.

12. bdf to check it. [/B]

谢谢你，写的真详细。有问题的话，我再向你请教。

If u haven\'t find the disk u installed in /dev/dsk
u should run insf before pvcreate
