The specific operation steps are as follows :
a) Check out the currently available hard drives :
# lspv
hdisk0 0002d74f0e69d97a rootvg
hdisk1 0002d74fea8ad09d none
hdisk2 000214dadca3a694 dbbakvg
hdisk3 0002d74f1e67ac3b dbbakvg
In this case ,hdisk0 It is the default hard disk after the system is installed , and hdisk1 The last property is shown as “none”, This means that this hard disk has not been VG Use , It can be used to do rootvg Mirror image .
b) Check hdisk1 Whether it can be regarded as a result of AIX Supported boot devices :
# bootinfo -B hdisk1
If this command returns the value 1, The selected disk can be AIX guide . Any other value represents hdisk1 No rootvg Candidates for making images .
c) Expand rootvg To include hdisk1:
# extendvg rootvg hdisk1 ;( If hisk1 Previously by others VG Used to , It can be used -f Parameters #extendvg -f rootvg hdisk1)
d) Cancel VG Physical volume quota management in ( stay VG As long as there is any PV It works , this VG You can use ):
# chvg -Qn rootvg
After running , Reuse lsvg rootvg see ,QUORUM The value of the item will be 1
e) Yes rootvg Do the mirror operation
# mirrorvg –c 2 rootvg
The time required for this work is related to rootvg It depends on the size of the space currently used , In practice ,95 GB Size , It was used 2 Hours .
f) stay rootvg Create boot information on two disks of
# bosboot –ad hdisk0
# bosboot –ad hdisk1
g) The order in which the device system starts the device
# bootlist–m normal hdisk0 hdisk1 cd0
Here we are ,rootvg The mirror work is done .
