1、Identify the loop_id of the disk being moved or replaced

# fcmsutil /dev/td0 devstat all | grep Loop
Device Statistics for Nport_id 0x0000ce(Loop_id 15)
Device Statistics for Nport_id 0x0000e0(Loop_id 5)
Device Statistics for Nport_id 0x0000e2(Loop_id 3)
Device Statistics for Nport_id 0x0000e4(Loop_id 2)
Device Statistics for Nport_id 0x0000e8(Loop_id 1)
Device Statistics for Nport_id 0x0000ef(Loop_id 0)

 

在系统中已经完全看不到了，所以可以直接换盘。

 

2、Replace bad disk with new disk.

 

3、Check the state of the new disk

# ioscan -fnC disk
Class     I  H/W Path      Driver S/W State   H/W Type     Description
=======================================================================
disk      2  0/0/1/0.2.0   sdisk  CLAIMED     DEVICE       HP      DVD-ROM 305
                          /dev/dsk/c0t2d0   /dev/rdsk/c0t2d0
disk      0  0/0/1/1.15.0  sdisk  CLAIMED     DEVICE       HP 36.4GST336753LC
                          /dev/dsk/c1t15d0   /dev/rdsk/c1t15d0

                          /dev/dsk/c4t3d0   /dev/rdsk/c4t3d0
disk      7  0/2/0/0.8.0.255.0.4.0  sdisk  CLAIMED     DEVICE       HP 36.4GST336752FC
                          /dev/dsk/c4t4d0   /dev/rdsk/c4t4d0

                          /dev/dsk/c4t5d0   /dev/rdsk/c4t5d0

 

4、Restore the LVM configuration/headers onto the replaced disk from your backup of the LVM configuration.

# vgcfgrestore -n /dev/vgsybase /dev/rdsk/c4t4d0
Volume Group configuration has been restored to /dev/rdsk/c4t4d0

 

5、Attach the new disk to the active volume group with the vgchange command.

# vgchange -a e /dev/vgsybase
Volume group "/dev/vgsybase" has been successfully changed.

 

6、Identify the loop_id of the new disk .

# fcmsutil /dev/td0 devstat all | grep Loop
Device Statistics for Nport_id 0x0000ce(Loop_id 15)
Device Statistics for Nport_id 0x0000e0(Loop_id 5)
Device Statistics for Nport_id 0x0000e1(Loop_id 4)
Device Statistics for Nport_id 0x0000e2(Loop_id 3)
Device Statistics for Nport_id 0x0000e4(Loop_id 2)
Device Statistics for Nport_id 0x0000e8(Loop_id 1)
Device Statistics for Nport_id 0x0000ef(Loop_id 0)

 

7、It's over
