Hi,
I have a Superdome 2 16s server. In this server i had 2 npars and each one, will define several vm's. I'm using the last release for Integrity VM on the npar:
vmGuestLib B.06.20 Integrity VM vmGuestLib
vmGuestSW B.06.20 Integrity VM vmGuestSW
vmKernel B.06.20 Integrity VM vmKernel
vmOVMMSW B.06.20 Integrity VM vmOVMMSW
vmProvider B.06.20 WBEM Provider for Integrity VM vmProvide
vmVirtProvider B.06.20 Integrity VM vmVirtProvider
My external disks comes from a Hitachi Storage Server that is connected to different fiber channel hbas installed in different IOX.
This fc hbas are managed by the Npar2:
sd16dom2_npar2# ioscan -fnkC fc
Class I H/W Path Driver S/W State H/W Type Description
=================================================================
fc 0 42/0/0/2/0/0/0/5/0/0/0 fclp CLAIMED INTERFACE HP AT094-60001 PCIe Fibre Channel 2-port 8Gb FC/2-port 10GBE Combo Adapter

/dev/fclp20
When i run the ioscan command on my Npar2, i can discover the disks that will assign to the vm1. In this case are 4 disks (disk21, disk22, disk23, disk24).

What is the recommended procedure for assign these disks to the vm 1 ??. I was reading the Integrity VM V 6.2 Administration Guide, but i have some dudes about the storage assigment to the vm's. I'm interesting in use the attached i/O method because i don't want to share these disks to others vm's on the npar2. In fact, i was thinking if is convenient to assign the 2 fc hba's hardware paths to the vm 1 and then discover directly these 4 disks since the vm 1 os ??. it's possible or is not necessary ??.
Thank's in advance
Ivan

Re: How to attaching disks to a integrity vm
There are tradeoffs as documented in the VM User Guide as to which "backing" method you choose to use.
For instace file backing although highly portable is not a good choice for high I/O devices. More suitable for DVD etc.
Then you have LVM backed storage. Where basically you create a volume group and logical volume and assign to a VM. these are better in performance than file backed, yet offer some versatility - like naming conventions. This makes each LV easy to identify as belonging to a VM.
Then there is disk backed storeage. Disk backed storage is even higher in performance than both LV and file backed storage. You basically assign the VM a "raw" disk device,which then shows up as a disk with IOSCAN from the VM guest.
With all of the above you will need to use the AVIO_STOR device
I believe 6.1 or 6.2 also introduced the NPIV feature allowing you to perform direct assignement of a SAN based volume to a VM guest. This would in theory be the best performer of the group, however I do not have much experience with this method. Most of my experiences are with the "raw" disk backed storage devices assigned to the VM guest. This gives you some granularity of control, but also offers good performance.
Bottom line the higher you go up the I/O stack on the VM host, the more performance hit you take on the guest. Which is why I would NOT recommend file backed storage for applications etc.
As for the exact commands, there are many examples in the config guide, once you decide which method you would prefer.

Re: How to attaching disks to a integrity vm
A pretty good read on the NPIV.
http://h20195.www2.hp.com/V2/GetPDF.aspx%2F4AA3-9894ENW.pdf
Link is for 6.1 version, I am looking for the 6.2 version as well.
"What is the recommended procedure for assign these disks to the vm 1 ??. I was reading the Integrity VM V 6.2 Administration Guide, but i have some dudes about the storage assigment to the vm's. I'm interesting in use the attached i/O method because i don't want to share these disks to others vm's on the npar2. In fact, i was thinking if is convenient to assign the 2 fc hba's hardware paths to the vm 1 and then discover directly these 4 disks since the vm 1 os ??. it's possible or is not necessary ??."
With the legacy AVIO you had to present ALL of the storage to the VM host, then either use file, LV or RAW backed storage and assign to the VM guest. With NPIV, you create a virtual HBA and you assign the HBA to the VM guest. This will provide the guest with a unigue WWN which you can then zone and provision SAN based volumes.
So yes, if you choose this mentod, you will be able to discover the volumes directly on the guest and there is no need to present the volumes to the host. Be aware though to read through the caveats in the NPIV document.

Re: How to attaching disks to a integrity vm
Thank's Jason, your information is very interesting and the NPIV is the best solution for me, but need to cover many prerequisites in hardware an software. By the way, is posible to have a mix environment , using NPIV for some virtual machines and the avio_stor for others ??.

Re: How to attaching disks to a integrity vm
Yes it is possible to mix and match VM storage on VM guests - even on the same VM guest. You can configure an NPIV-based LUN as a boot disk, use AVIO LUNs as data disks, use LVM logical volumes, file-based backing stores, NFS-based backing stores, etc. There is no requirement to use only one storage type.
I prefer to use NPIV whole LUNs or AVIO whole LUNs as they perform better than LVM, file, NFS-based backing stores.

Re: How to attaching disks to a integrity vm
By the way, i'm triying to attach a disk using the avio procedure:
# hpvmmodify -p 1 -a disk:avio_stor::disk:/dev/rdisk/disk21
that's correct ??.

Re: How to attaching disks to a integrity vm
Assuming you want to add the whole disk /dev/rdisk/disk21 to guest #1 via AVIO, yes that syntax looks correct.

Re: How to attaching disks to a integrity vm
Hi, i'm starting to install the NPIV on my npar and vm. But i'm having a connection problem between the server and client. This is the message:
# /opt/guid/bin/guid_client_prepare -a
NOTE:
We found Host is configured in /opt/guid/etc/guid.conf. This
may because current machine has been once installed and
configured as a GUID client. Or user has defined hostname in
guid.conf by CLI tool "guidconfig -h".
In this case, we only try setting up authentications between
current client and remote GUID servers, which are configured
in HOST.
Install pubkey on GUID server(sd16dom2) succeeded.
Connect to host sd16dom2 failed. ---> NOTE: BOTH SERVERS ARE IN THE SAME SUBNET
ListRange of wwn from GUID server(sd16dom2) failed.
GUIDMGR client preparation accomplished.
Some suggestion ??.

Re: How to attaching disks to a integrity vm
I assume you have a GUID manager configured at this point and have created a range of WWN values. You can try manually setting the hostname of the GUID manager using "guidconfig -h" and then see if you can query the GUID manager to display the list of managed WWN ranges:
# /opt/guid/bin/guidconfig -h <hostname of GUID manager>
# /opt/guid/bin/guidmgmt -L wwn

SolutionBonjour,
Not sure that everybody will agree with that : you can also manage manually NPIV WWN.
Extract from HP-UX vPars 6.0 N-Port ID Virtualization (NPIV), bottom of page 9 :
Allocating IDs manually or with third-party products
When manually configuring vHBAs, vWWNs may safely be picked from the range 0x100000110a0300 - 0x100000110a030fff. This is a total of 4096 WWN which are not in the range that is handled automatically by GUIDMgr (see above). A user may use GUIDMgr for some NPIV HBAs and still manually select from the above range for other vHBAs. If this is being done, please note that you can save your manual settings in the GUIDMgr for tracking purposes, but the GUIDMgr never assigns a WWN outside of the range that HP has reserved.
Note there is a typo : range should begin @ 0x100000110a030000. Two zeroes are missing.
Don't know how many virtual HBA you will have to manage, but it could be easier to maintain an Excel spreadsheet. That's what I do : I don't want to have to maintain an additional software layer if I can avoid it.

Re: How to attaching disks to a integrity vm
Opps, sorry by the delay. In fact i',m triying to install my NPIV scenario by first time. Here we go:
a) In the NPAR and VM servers i'm following the next procedure from the manual:
2.2.1 Installing on the server
To install the HP-UX GUID Manager software on the database server, enter the following command
on the server:
#
swinstall -s ${DEPOT_PATH}/GUIDMGR_A.01.00.603_HP-UX_B.11.31_IA.depot GUIDMGR
#
swlist GUIDMGR
GUIDMGR A.01.00.603 HP-UX GUID Manager
This command initializes the GUIDMgr server-side environment, including creating a GUID private
user account, initializing the database, and starting the database service. If no error occurs during
initialization, GUIDMgr related daemons are started. If any error occurs, you must fix the error
before performing the next step or distributing current host name to any GUIDMgr client.
To initialize the server, enter the following command:
#
/opt/guid/utils/guid_server_prepare.sh
This command configures the GUIDMgr on the target system. After the GUID Manager is configured
on the server, the database is empty. The
guid_server_prepare command creates some guid
tables without any guid data. The guid_server_prepare.sh script executes the following commands
automatically:
2.1 Installation requirements 9
•
/opt/guid/bin/guidconfig –b wwn is executed to set up the library linkage for the
commands.
•
/opt/guid/sbin/guidd is started as the main daemon for a GUID server.
•
/opt/guid/sbin/guidkeyd is started, so you can SSH tunnel to GUID server from GUID
client.
•
/opt/guid/sbin/guiddbutil –c wwn is used to create the initial database, if not
already created.
The
/opt/guid/tools/postgresql directory contains binaries to set up the a postgresql
database for private use by a GUID server. Various PostgreSQL commands are executed to set up
the database for the first time, if not already created, and start the
postgresql daemons needed
to access the database.
2.2.2 Installing on the client
To install the GUID client, enter the following command on all the VSP hosts:
#
swinstall -s ${DEPOT_PATH}/GUIDMGR_A.01.00.603_HP-UX_B.11.31_IA.depot GUIDMGR
NOTE:
After installing and verifying the client installation, you must set up authentication on
GUID client. Otherwise, any GUID request to remote server will fail. See
“Verifying the installation
of GUIDMgr” (page 10) for information about setting up authentication.
3.1 Setting up the server and the client
This section provides the steps for setting up the server and the client. After installing, initializing,
and configuring the GUID manager on the server (see “Installing on the server” (page 9)), follow
these steps to set up the server:
1.
Set the GUIDMgr server hostname:
#
/opt/guid/bin/guidconfig -h guid_server_hostname
After installing GUID Manager on the client “Installing on the client” (page 10), perform the
following steps to set up the client:
1.
Configure client access to the database:
#
/opt/guid/bin/guid_client_prepare -a
2.
Set the GUIDMgr server hostname:
#
/opt/guid/bin/guidconfig -h guid_server_hostname
3.
Create a range of WWNs to manage:
#
/opt/guid/bin/guidmgmt -S wwn 50014c2000000000 50014c2000007fff
4.
Verify database access by querying the pools of WWNs:
#
/opt/guid/bin/guidmgmt -L wwn
Range type Start(Hex) End(Hex) Size(dec)
=============== ================== ================== ==========
HP-DEFINED-PWWN 0x50014c2000000000 0x50014c2000007fff 32768
HP-DEFINED-NWWN 0x50014c2800000000 0x50014c2800007fff 32768
5.
Verify ranges with these commands:
#
/opt/guid/sbin/guiddbutil -s range_wwn wwn
#
/opt/guid/sbin/guiddbutil -s addr_wwn wwn
3.2 Verify
But this procedure isn't working for me because i obtain the same result on the vm :
# /opt/guid/bin/guid_client_prepare -a
NOTE:
We found Host is configured in /opt/guid/etc/guid.conf. This
may because current machine has been once installed and
configured as a GUID client. Or user has defined hostname in
guid.conf by CLI tool "guidconfig -h".
In this case, we only try setting up authentications between
current client and remote GUID servers, which are configured
in HOST.
Install pubkey on GUID server(sd16dom2) succeeded.
Connect to host sd16dom2 failed.
ListRange of wwn from GUID server(sd16dom2) failed.
GUIDMGR client preparation accomplished.
Some idea ??

Re: How to attaching disks to a integrity vm
Check the attached spreadsheet ... my own GUI ;-) Of course, I can't assume any bug. It's just a tool for myself I can share
Just add the name of the vm guest you want to modify, the virtual bus where you want to connect the virtual hba, the physical hba on the host and you will find all the commands to modify the vm guest and to add the corresponding host in a 3Par storage.
If you add the existing aliases of a storage in the san, you will get commands to create the corresponding zones in the fabrics
Fabric number is optional. Just a way to color the commands for the fabrics.
