如何创建lpar通过HMC/VIOS(动态加disk)

以下描述了如何创建lpar通过HMC/VIOS(动态加disk)，lpar是系统盘是通过dd一个已经装好aix的LV. 已经装好aix的LV，这个相当于镜像。可以用这个镜像dd出一个系统盘，然后用作lpar的系统盘，再动态挂载一个数据盘，然后卸载系统盘，然后全部清除掉。

这个过程尽量match虚拟机管理的一般流程。

1. create lv on vios

mklv -lv lvdisk1 rootvg 50G

lsvg -lv rootvg

//on vios, dd lvdisk1 from image(lv_testrvg)

lsmap -all -type disk lv

oem_setup_env

dd if=/dev/lv_testrvg of=/dev/lvdisk1 bs=1m

2. create vscsi server of vios on HMC

chhwres -r virtualio -m Server-8231-E2B-SN064B14R -o a -p vios --rsubtype scsi -a "adapter_type=server"

lshwres -r virtualio -m Server-8231-E2B-SN064B14R --level lpar --rsubtype scsi --filter "lpar_names=vios"

lpar_name=vios,lpar_id=2,slot_num=3,state=1,is_required=0,adapter_type=server,remote_lpar_id=any,remote_lpar_name=,remote_slot_num=any

lpar_name=vios,lpar_id=2,slot_num=5,state=1,is_required=0,adapter_type=server,remote_lpar_id=any,remote_lpar_name=,remote_slot_num=any

lpar_name=vios,lpar_id=2,slot_num=6,state=1,is_required=0,adapter_type=server,remote_lpar_id=4,remote_lpar_name=null,remote_slot_num=2

lpar_name=vios,lpar_id=2,slot_num=7,state=1,is_required=0,adapter_type=server,remote_lpar_id=any,remote_lpar_name=,remote_slot_num=any

3. mkvdev on vios

$ lsdev -slots

# Slot                   Description       Device(s)

U8231.E2B.064B14R-V2-C0  Virtual I/O Slot  vsa0 

U8231.E2B.064B14R-V2-C2  Virtual I/O Slot  ent4 

U8231.E2B.064B14R-V2-C3  Virtual I/O Slot  vhost0 

U8231.E2B.064B14R-V2-C4  Virtual I/O Slot  vfchost0 

U8231.E2B.064B14R-V2-C5  Virtual I/O Slot  vhost1 

U8231.E2B.064B14R-V2-C6  Virtual I/O Slot  vhost2 

U8231.E2B.064B14R-V2-C7  Virtual I/O Slot  vhost3

mkvdev -vdev lv_jzhao -vadapter vhost3 -dev vc_disk1   //lv_jzhao is the lv disk after dd

4. create lpar

lsmap -all -net //on vios, get vlan

mksyscfg -r lpar -m Server-8231-E2B-SN064B14R -i "name=jzhaovm1,profile_name=jzhaovm1,lpar_env=aixlinux,min_mem=256,desired_mem=1024,max_mem=1024,proc_mode=ded,min_procs=1,desired_procs=1,max_procs=2,sharing_mode=share_idle_procs,boot_mode=norm,virtual_scsi_adapters=2/client/2/vios/7/0,virtual_eth_adapters=3/0/1//0/0,max_virtual_slots=20"

lssyscfg -m Server-8231-E2B-SN064B14R -r prof

lssyscfg -r lpar -m Server-8231-E2B-SN064B14R -F name:lpar_id:state

chsysstate -m Server-8231-E2B-SN064B14R -r lpar -o on --id 4 -f jzhaovm1

5. access AIX

telnet 10.0.xx.xx

lsdev -Cc disk

6. add second disk

//on vios

mklv -lv lvdisk2 rootvg 15G

lsvg -lv rootvg

//create vscsi server of vios on HMC

chhwres -r virtualio -m Server-8231-E2B-SN064B14R -o a -p vios --rsubtype scsi -a "adapter_type=server"

lshwres -r virtualio -m Server-8231-E2B-SN064B14R --level lpar --rsubtype scsi --filter "lpar_names=vios"

on vios: mkvdev -vdev lvdisk2 -vadapter vhost4 -dev vc_disk2

# vhost4 is related with vios vscsi server slot.

lpar: add vscsi cleint

//on HMC 

chhwres -r virtualio -m Server-8231-E2B-SN064B14R -o a -p jzhaovm1 --rsubtype scsi -a "adapter_type=client,,remote_lpar_name=vios,remote_slot_num=8"

lshwres -r virtualio -m Server-8231-E2B-SN064B14R --level lpar --rsubtype scsi --filter "lpar_names=jzhaovm1"

//on lpar:

cfgmgr

# lsdev -Cc disk

hdisk0 Defined    Virtual SCSI Disk Drive

hdisk1 Available  Virtual SCSI Disk Drive

hdisk2 Available  Virtual SCSI Disk Drive

7. unattach second disk

//on lpar:

lsdev

rmdev -dl hdisk2

rmdev -Rdl vscsi1

hdisk2 deleted

vscsi1 deleted

//on HMC

lshwres -r virtualio --rsubtype scsi -m Server-8231-E2B-SN064B14R --level lpar

chhwres -r virtualio -m Server-8231-E2B-SN064B14R -o r -p jzhaovm1 --rsubtype scsi -s 4

rmvdev -vtd vc_disk2   //on vios

chhwres -r virtualio -m Server-8231-E2B-SN064B14R -o r -p vios --rsubtype scsi -s 8   //for disk2 of lpar

8. remove lpar on HMC

chsysstate -r lpar -m Server-8231-E2B-SN064B14R -n jzhaovm1 -o shutdown --immed

rmsyscfg -r lpar -m Server-8231-E2B-SN064B14R -n jzhaovm1

rmvdev -vtd vc_disk1  //on vios

chhwres -r virtualio -m Server-8231-E2B-SN064B14R -o r -p vios --rsubtype scsi -s 7

9. remove lv disk on vios

rmlv lv_disk2

10. other command:

lscfg -vpl hdiskX

lssyscfg -m SVRP8-S822-03-SN847A74V -r prof

bootinfo -s hdiskX

lsdev -Cc disk
