IDEで作ったNutanix上のVMをscsiに変換してみた。
念のため作業前にVMのsnap shotは取得しておきます。

まずは、Nutanix clusterのCVMに入り対象を確認

# acli
vm.get hoge-vm-01
hoge-vm-01 {
config {
agent_vm: False
allow_live_migrate: True
boot {
device {
disk_addr {
bus: "ide"
index: 1
}
}
uefi_boot: False
}
disk_list {
addr {
bus: "ide"
index: 0
}
cdrom: True
device_uuid: "31334ace-7c53-464d-9492-f5ea86e49ce6"
empty: True
}
disk_list {
addr {
bus: "ide" ←変換対象はこれ
index: 1
}

}

対象が分かったらideからscsiに変換します。

vm.disk_create hoge-vm-01 bus=scsi clone_from_vmdisk=vm:hoge-vm-01:ide.1
DiskCreate: complete

確認します。

vm.get hoge-vm-01
hoge-vm-01 {

変換できてるようです。

元のディスクを削除します。
タブ連打で出てくるのでacliのコマンドモードは便利です。

vm.disk_delete hoge-vm-01 disk_addr=
ide.0 ide.1 scsi.0
vm.disk_delete hoge-vm-01 disk_addr=ide.1
Delete existing disk? (yes/no) yes
DiskDelete: complete

再度確認

vm.get hoge-vm-01
hoge-vm-01 {
config {
agent_vm: False
allow_live_migrate: True
disk_list {
addr {
bus: "ide"
index: 0
}
cdrom: True
device_uuid: "31334ace-7c53-464d-9492-f5ea86e49ce6"

変換完了です。

Nutanix上に構築したVMのMACアドレス変更手順メモ

現在のVMのMACアドレスを確認

# nmcli device show eth0| grep HWADDR
GENERAL.HWADDR: 50:6B:8D:8C:CC:52

50:6b:8d:8c:cc:52が割当たっています。

次にCVM上から確認　acliを使います。

$ acli

vm.nic_get Centos7_test
192.168.200.101 {
ip_address: "192.168.200.101"
mac_addr: "50:6b:8d:8c:cc:52"　←確認
network_name: "vlan0"
network_uuid: "75c0ba81-ff8d-4aac-a854-c94586483b4b"
type: "kNormalNic"
vlan_mode: "kAccess"
}

vm.nic_deleteコマンドで一度VMからNICを削除します。

$ vm.nic_delete Centos7_test 50:6b:8d:8c:cc:52

つぎにvm.nic_createでVMを指定して変更したい任意のMACアドレスをNICに割り当てます。
今回は50:6b:8d:8c:cc:55を割り当てます。

$ vm.nic_create Centos7_test mac=50:6b:8d:8c:cc:55 network=vlan0 request_ip=false

acliで確認します。

vm.nic_get Centos7_test
50:6b:8d:8c:cc:55 {
mac_addr: "50:6b:8d:8c:cc:55"　←変更されている
network_name: "vlan0"
network_uuid: "75c0ba81-ff8d-4aac-a854-c94586483b4b"
type: "kNormalNic"
}

更にVMからも確認
変更確認

[root@cent7-test ~]# nmcli device show eth0| grep HWADDR
GENERAL.HWADDR: 50:6B:8D:8C:CC:55

おしまい

NutanixのCVMのhostnameをあとから変更するメモ

まずはhostnameを変えたいCVMにログイン
NTNX-aaaaa-CVMからNUTANIX-01-CVMに変えます。

Nutanix Controller VM
Last login: Fri Sep 11 20:05:23 2018
nutanix@NTNX-aaaaa-CVM:172.10.5.5:~$ /usr/local/nutanix/cluster/bin/change_cvm_hostname NUTANIX-01-CVM
Script must be run as root

nutanixユーザーでは実行できません。

sudoで実行

nutanix@NTNX-aaaaa-CVM:172.10.5.5:~$ sudo /usr/local/nutanix/cluster/bin/change_cvm_hostname NUTANIX-01-CVM
Changing hostname to NUTANIX-01-CVM. This will reboot the CVM. Do you want to proceed? (Y/N): y

これで変更完了
