Replace the mirror hard drive
Mirror mirrored disk replacement
General steps: remove the image of mirror-- and delete the broken hard disk-add a new hard disk to rootvg-- to do mirror mirror synchronization (usually synchronize yourself)
First, check the point of failure
# lsvg-p rootvg
Rootvg:
PV_NAMEPV STATETOTAL PPSFREE PPSFREE DISTRIBUTION
Hdisk1active546
Hdisk0missing546
Hdisk2active546
-- hdisk0 disk malfunctioned
2. Remove the mirror image
Unmirrorvg rootvg hdisk0
If lg_dumplv is on hdisk0, you need to move it to hdisk1
Dump device description:
If the system has a proprietary dump device, you need to create a new dump device on the left hard disk and reassign the basic dump device to a logical volume that leaves the hard disk. For example, after completing the "unmirrorvg" command, you will see:
# lspv-l hdisk0
Dumplv
Now you can move "dumplv" from hdisk0 to hdisk1 with the "migratepv" command:
# migratepv-l dumplv hdisk0 hdisk1
Or migratepv-l lg_dumplv hdisk0 hdisk1.
4. Clean up the boot information on hdisk0
# chpv-c hdisk0
3 check the boot sequence and modify it to hdisk1 boot
# bootlist-m normal-o
Hdisk0
Hdisk1 blv=hd5
# bosboot-ad hdisk1
# bootlist-m normal hdisk1
# bootlist-m normal-o
Hdisk1 blv=hd5// confirms that the system can boot from hdisk1
Remove hdisk0 from rootvg
Reducevg rootvg hdisk0
VI. Delete hdisk0
Rmdev-Rd1 hdisk0
7. Check whether lspv still exists in hdisk0
Lscfg-vl hdisk0
# lsdev-Cc disk// confirms that hdisk0 has been deleted
Delete a bad hard drive
# diag
# Task Selection
# Hot Plug Task
# SCSI and SCSI RAID Hot Plug Manager
# replace/remove a device attached to an SCSI Hot Swap
# hdisk0
Usually hdisk0 will light up and replace the hard disk.
9. After installing the new hard drive
# cfgmgr-v scan hard disk
Lspv View
# lspv
Hdisk1 00c58faf7b68fccc None
Hdisk0 00c58faf8b32fef3 rootvg active
If there is no PVID, execute chdev-l hdisk1 pv=yes or chdev-l hdisk0-a pv=yes
# lspv
Hdisk0 000f377fc4df58cb rootvg active
Hdisk1 000f377f19224090 rootvg active
Hdisk2 none None
10. Make an image
Add hdisk0 to rootvg
# extendvg rootvg hdisk0
Make a rootvg image
# mirrorvg-S rootvg hdisk0
# View rootvg
Lsvg-l rootvg
# add startup information boot image to the newly added disk hdisk0
Bosboot-ad / dev/hdisk0
# modify the startup sequence
Bootlist-m normal hdisk0 hdisk1
# View
Bootlist-m normal-o
Lspv-l checks whether the disk is automatically synchronized. If not, execute syncvg-v rootvg.
