Mirroring the rootvg Volume Group for AIX

** Myself
เป็น shell script ที่ใช้ในการ mirror logical volume ของ AIX เมื่อมีการเปลี่ยน disk หรือมีการเพื่มครับ

#Mirroring the rootvg Volume Group for AIX
#--------------------------------------------------------------------------------
# 1. Extend rootvg to ${SEC_DISK}:
PRI_DISK=hdisk0
SEC_DISK=hdisk1




extendvg rootvg ${SEC_DISK}
#
# Command reduce vg is
# reducevg rootvg ${SEC_DISK}
#
# 2. Disable QUORUM, by running the following:

chvg -Qn rootvg

# 3. Mirror the logical volumes that make up the AIX operating system:
# mklvcopy hd1 2 ${SEC_DISK} # /home file system
# mklvcopy hd2 2 ${SEC_DISK} # /usr file system
# mklvcopy hd3 2 ${SEC_DISK} # /tmp file system
# mklvcopy hd4 2 ${SEC_DISK} # / (root) file system
# mklvcopy hd5 2 ${SEC_DISK} # blv, boot logical volume
# mklvcopy hd6 2 ${SEC_DISK} # paging space(if the user has other paging devices, rootvg and non-rootvg, they
# must also mirror those logical volumes in addition to hd6)
# mklvcopy hd8 2 ${SEC_DISK} # file system log
# mklvcopy hd9var 2 ${SEC_DISK} # /var file system
# If hd5 consists of more than one logical partition, then after mirroring hd5 the user must verify that the mirrored copy of hd5
# resides on contiguous physical partitions. This can be verified with the command:
# lslv -m hd5
#
# If the mirrored hd5 partitions are not contiguous, then the user must delete the mirror copy of hd5 (on ${SEC_DISK}) and rerun the mklvcopy for
# hd5 using the "-m" option. The user should consult documentation on the usage of the "-m" option for mklvcopy.

ldisk=$(ls /dev/hd[1-9]* |cut -d "/" -f 3)
for i in $ldisk
do
mklvcopy $i 2 ${SEC_DISK}
done

# Command unmirror rootvg is (and turn on quorum after reboot)
# unmirrorvg rootvg ${SEC_DISK}
# 4. Synchronize the newly created mirrors:

syncvg -v rootvg

# 5. Bosboot to initialize all boot records and devices:

bosboot -ad ${SEC_DISK}

# 6. Initialize the boot list:
bootlist -om normal ${PRI_DISK} ${SEC_DISK}
# 7. Shutdown and reboot the system:
shutdown -Fr
