Part I : HMC/vHMC/Enhanced GUI

PART II : Live Partition Mobility

Introduction

• Do you use an HMC?

• Lots of them?

• Many sessions about HMCs and how to do things with them

• Reflects on some of the options

– EG: when to use physical or virtual

3

What is the HMC for?

• Control/manage/monitor POWER Servers

• Deploy power servers

• Deploy LPARs

• Deploy VIOS

• DHCP for FSP

• Callhome

4

What hardware should I use?

• Intel based 7042-CR9

• Power based 7063-CR1

• Virtualised Intel server

• Virtualised POWER8 server

– If so, where/on what?

• You can probably guess what we will advise, but let’s look at it …..

7042-CR9 HMC Details

▪ For POWER6 and later servers

▪ 7042-CR9 --- follow-on to 7042-CR8

▪ Normal technology refresh

▪ Similar price to CR8

▪ Refreshed rack-mounted HMC– 2.4GHz Intel Xeon Processor

– 16GB to 192GB memory (#EM20 16GB feature code) – Most clients expected to use 16GB or 32GB for HMC

– One or optionally two 500GB SATA disk drives– Second drive allows RAID1 mirroring protection (recommended/defaulted)

– Support any two of the eight physical hot-plug SFF bays (max 2 supported)

– DVD-RAM

– Four integrated Ethernet ports

– Six USB ports

– One PCIe slot

– One or two power supplies (two recommended for hot-plug redundancy)

– 1U (1 EIA)

– Like CR8, does not offer an internal or external modem (or support one)

▪ HMC code level 8.4.0 or later

▪ 1U (1EA) rails included with CR9 (no separate feature code)

HMC 7063-CR1 GA 4Q2017

▪ 7063-CR1 is based on System S821LC▪ Fixed Config

▪ 6 POWER8 cores with SMT8

▪ 32GB RAM

▪ 2 HDD

▪ Fits round holes and square holes

▪ Simple to install, remotely start/stop using BMC + ipmitool + web UI

▪ GA with HMC V8.870: 4Q 2017

7063-CR1 has a lower list

price than 7042-CR9

HMC Virtual Appliance Details .

▪ IBM Virtual HMC Complete Software offering – License plus software maintenance– PID – 5765-HMV– Approximately $4k CDN including 1 year SW maint

▪ Virtual HMC Runs – On x86 Hardware (provided by client)– x86 64-bit with Intel VT-x or AMD-V– 4 CPU, 8 GB memory, 160GB disk (500GB recommended), 2 NIC– Under KVM or VMware virtualization (provided by client)

▪ New vHMC Complete Software offering – Activation engine – provides configuration on first boot– Accept License, locale, network, SSH, NTP

▪ Manages any POWER6 or later Power servers▪ Version 8 HMC firmware▪ Can be used with or without hardware HMCs

POWER8 virtual HMC

• POWER8 virtual HMC – like the Intel vHMC

• Runs in a PowerVM LPAR on a POWER8 server

– No, it will not run on a POWER7 processor

– Yes, it will manage a POWER7 based server

• Obviously, you can’t manage the server its actually running on!

• Note: not KVM, XEN, Vmware

9

Can I use both Intel and POWER8 HMCs

• YES

• A server can be managed by 2 HMCs

• Any combination of Intel/POWER

• Any combination of hardware appliance/software appliance

• Do not think about using a vHMC in a PowerVM LPAR on a server which

the HMC manages

• Allowed this time only one HMC at 860 + one HMC at 870

– Normally both HMC must be at exactly the same level

10

HMC V8R870

• No Classic GUI

• Enhanced+ GUI has all functionality that was in Classic

• Runs on Intel or POWER8

• Manages

– POWER6

– POWER7

– POWER8

• HMC V8 will not manage POWER9 based servers

– So use the Enhanced+ GUI now

11

I want to use the Classic GUI

• You can

– But only up to HMC V8 R860

– Support continues till end of 2018

– Then the only supported GUI will be Enhanced+

– HMC V8 will not manage POWER9 based servers

12

Navigating through Enhanced UI

My counterpart in the UK, Nigel Griffiths, has done a really nice job covering this in a 10 part series. https://www.youtube.com/user/nigelargriffiths

• PART II Live Partition Mobility

16

LPM Benefits

• Simplify server upgrades with no down time

- Move running partitions to newer servers

• Better system utilization

- Quickly balance workloads and resources as needs change

• Improved application availability

- Eliminate downtime for planned system maintenance

• Energy savings

- Consolidate workloads to fewer servers when possible and turn off idle systems

While LPM improves system availability, it is not a solution for unplanned outages.

Continue using high availability solutions.

PowerVM™ Live Partition Mobility

Hypervisor

What is LPM?▪Relocate an entire LPAR

between physical chassis

▪Requires POWER6™ or

better

▪LPARs continue to run and

provide services to clients,

who are completely unaware

of the migration

▪Final suspension and

resumption of LPAR is

guaranteed to be less than 2

seconds

Migration: active or inactive

Active migration: partition migration is performed with the operating system and applications running, without disrupting operations

Inactive migration: partition is not running when it is moved to the target system

Active

• Validate configuration• Create new LPAR• Create new virtual resources• Migrate state of LPAR in memory• Remove old LPAR configuration• Free up old resources

Inactive

• Validate configuration• Create new LPAR• Create new virtual resources• Remove old LPAR configuration• Free up old resources

Summary of Migration Phases

19

Mobile partition requirements checklist (1 of 2)

Check mobile partition configuration:

✓ Operating system support

✓ Functioning RMC daemons

✓ No huge memory pages*

✓ No Barrier Synchronization Register arrays* (BSR)

✓ No workload group

✓ No redundant error reporting*

✓ No open consoles (warning only)

✓ Storage on external storage unit and accessible by both VIOS LPARs

✓ Check that LPAR name will be unique on destination server

* Okay for inactive migrations

20

Mobile partition requirements checklist (2 of 2)

Check mobile partition configuration (cont.):

✓ Check MAC address will be unique on destination server

✓ Not a service partition

✓ No physical I/O*

✓ No logical ports configuration on Integrated Virtual Ethernet (IVE)/Host Ethernet Adapter or SR-IOV (unless using vNIC)

– AIX 6100-05 (or higher) clients can convert LHEA to virtual Ethernet during migration

✓ Verify valid processor compatibility mode

✓ Virtual network configuration compatible with destination VIOS

* Okay for inactive migrations

21

For HMC Classic GUI, select partition and run Operations -> Mobility -> Migrate (or Validate)

HMC Enhanced+ Example

LPM migration operation (2 of 2)

Validate task provides one panel validation and

PowerVM LPM and Simplified Remote Restart Automation Tool (1 of 3)

IBM Lab Services GUI for managing migrations

– POWER7 and POWER8 migrations

– Linux, AIX, and Windows versions

– Browser-based with reduced clicks!

The tool version numbering now matches the features of the highest HMC version it can exploit

– In use since 2014

Download from Resource Link, unzip, add your HMC, and it discovers your servers and LPARs

– Need to contract with Lab Services

Uses SSH to direct HMCs to do migrations

26

PowerVM LPM and Simplified Remote Restart Automation Tool (2 of 3)

LPM tool features:

– Evacuate a server to one or multiple servers

– Move groups of partitions

– Can “Pack” or “Stripe” LPARs to destination servers

– Maintain concept of “original” server for mobile partitions

– Create migration plans and deploy plans during service windows

– Export validation details to a spreadsheet

– Many GUI features only available on HMC command line: vSwitch, vNIC, NPIV LUN validation, SR-IOV, concurrency levels, etc.

• Easy to maintain virtual adapter IDs and FC port ID assignments

SRR tool features:

– In case of server outage, restart its LPARs on a remote server

– Configuration details of the LPAR is kept on disk to quickly get it running on remote server

– After downed server is up and running, a few clicks will get original LPARs migrated back with LPM

– Without automation tool, SRR is available only on HMC CLI 27
