ISCSI LUNs presented as online on new server for new cluster.

We are building out a new 2012 R2 Hyper-V cluster. The old environment is a mix of Cluster Shared Volume drives and LUNs presented just for the a VM itself.
I had planned on presenting everything in the old environment to the new environment and then just using the cluster migration wizard to move VM's over a few at a time.
I ran into a problem when I connected my first host to our SAN today. It is in a group that has over 70 LUN's presented to it. Once I connect to the target the host just cripples. I am not having Memory or CPU issues but Disk IO issues.
I noticed that the host now sees all 70 plus LUNs and has tried to bring those disk online as well.
I don't want them online right now. I just need the quorum drive and a few of the newly created LUN's online to finish creating our Cluster so we can start migrations.
Why is the Host trying to bring these drives online? As soon as I click on Devices in the iSCSI initiator the program locks up and doesn't respond.
Is there a way to setup the target but force the OS not to bring any of those disk online? I removed the favorite target, and there are no items listed in the Volume List under Volumes and Devices. However if you go to Disk Manager it shows all
70 plus disk and most of them now show online except for my newly created LUNs which are not initialized yet.

Hi KristopherJTurner,
You can try to remove the issue occurred hosts from iSCSI target SAN first. The iSCSI initiator first logs on to the target which the target has grant access before the server
can start reading and writing to all LUNs that are assigned to that target.

Have a dedicated TFTP Server for CCM cluster

Hi,
One CCM3.3(3) cluster in production, in which the publisher server was the TFPT server.
Now we need expend the system and would like to deploy a dedicated TFTP Server for the cluster. Is there anyone telling me what I should concern if I have a dedicated TFTP server other than the publisher server?
Thanks,
JJ

Hi,
I have a similar issue. I have actually a pub and a sub, the pub is also the tftp server. Following the SRND, I need a dedicated tftp server because we're almost at 1250 users, growing every day. My question, which may seem very basic, is how do I build a dedicated tftp server ?

Using iscsi luns as vdiskserverdevices

Hi
I am new to LDoms and was wondering if anyone has any experience of using iscsi luns (presented by zfs volumes on an X4500) as vdiskserverdevices . In my case the iscsi luns were presented to the service domain (in this case the control domain) and were correctly visible and accessible from it. However when presented as vdisks to the guest domains, for use as the root disk, the guest domains could not access/see the disks. When the guest domain was booted for a jumpstart install one of the first messages was that it couldn't access the vdisks and this was confirmed during the install process when a boot disk couldn't be found. AFAIK solaris can't boot of iscsi luns (without iscsi HBA's) but I figured that hiding the iscsi lun behind the vdiskserver would work -but no such luck. Any advice on whether this is possible would be most welcome.
As an unwanted work-around I created a couple of large files (aprox 420 Gb and 920Gb) and presented these instead as the vdsdevs. This time the smaller 420Gb couldn't be seen at all by the guest domain while the larger file showed up as a SUN 920Gb type disk though while partitioning it, it only showed about 100Gb as the disk size. Any pointers as to what I'm doing wrong here is also most welcome.
My hardware consists of 2* T5220 running Sol10 08/07 with latest recommended patches and firmware and an X4500 which is being used to provide all (root and data) storage for the guest domains.
Thanks
Saurav

Hi there,
I am setting up a platform when the guest domains are installed into iSCSI LUNS and it is working fine.
I am using LUN's expported from a NetApp rather than using ZFS but that shouldn't matter. They appear like this on my test platform:
root@solarisvh # iscsiadm list target -S
Target: iqn.1992-08.com.netapp:sn.********
        Alias: -
        TPGT: 2000
        ISID: 4000002a0000
        Connections: 1
        LUN: 0
             Vendor: NETAPP
             Product: LUN
             OS Device Name: /dev/rdsk/c4t0d0s2And I can add it into a guest domain by running:
ldm add-vdsdev /dev/rdsk/c4t0d0s2 examplevol1@primary-vds0I found that I had to pop in an label the disk (using format) on the first use for it to be picked up but after that it worked fine and I could boot up and install an OS into the LUN.

Moving ESX hosts to a new cluster?

I have 6 ESX 3.5.0 systems currently divided into three 2-node clusters.
Cluster 1 is HP DL380 G6 with Xeon E5540 CPU's and is not licensed for vMotion
Cluster 2 is HP DL380 G7 with Xeon X5650 CPU's and is licensed for vMotion
Cluster 3 if HP DL380 G6 with Xeon E5520 CPU's and is licensed for vMotion
All nodes are live and in production. Recently while enabling hyperthreading on nodes of cluster 2, the manual failovers didn't go well and we had a lot of downtime while systems fought for resources. HA has admission control enabled and 1 host failover capacity so I'm not sure why we had such extreme problems. Based on that issue, I'd like to create a larger cluster if possible but that brings a series of questions:
1) What nodes are hardware compatible to create a larger cluster? It looks like the nodes from 1 and 3 can be combined into one four node cluster but the CPU's are too different in cluster 2 to join them. Is that correct?
2) What implications are there of moving nodes to a new cluster? These are running VM's in a production environment, unplanned downtime is not tolerated (but planned is usually OK). It looks like I can just put a node into maintenance mode, remove it from a cluster, and then re-add it to a new cluster? If I license the nodes on cluster 1 for vMotion before this work, can that be done with no guest downtime?
Any gotcha's?
Everything is scheduled to be replaced later this year (new servers, VMware, and SAN) but with the failovers not working smoothly on cluster 2, I'd like to get this fixed as much as possible as soon as possible, with of course as little cash outlay as possible.
Thanks for any insight you can provide!

Hi,
As you have new servers I recommend you :
- Install OEL 5 on these new server ( OEL 6 is not supported)
- Install Oracle Clusterware 11.2.0.3
- Install Oracle Database 11.1.0.7
- Configure temporary Virtual IP (at moment of migration you can reconfigure these Virtual IP with same used on old cluster)
- Create a New Database with same name from actual PROD env using DBCA
- Configure Services and Network
- So remove only database files (Spfile, Control, Datafiles, Online Logs) from this new database created
At moment of Migration of Servers:
- Shutdown the Old Cluster
- Configure the Virtual IP of old cluster on new Cluster / Also you will need reconfigure Listeners and Tnsnames.ora
- Map the Luns of Database Files on new Cluster and mount your filesystem
- Start Database and all depend resources.
I recommend you use Grid Infrastructure (clusterware) 11.2 because if you in the future want upgrade your database to 11.2, you will need only install a Oracle RAC 11.2 and Upgrade your Database from 11.1.
If you install Clusterware 11.1 you will need upgrade both (Clusterware and RAC). It is much more work and you can find much more trouble to UPGRADE Clusterware, than performing a fresh installation.
Oracle Clusterware 11.2 Support (Oracle RAC 9i/10g/11g)
Any problem during these step at moment of migration you will have the old cluster.
Open an SR in the MoS to validate this new structure and migration.(This will help with possible problems that may occur)

Install OVM server 3.2.1 on iSCSI LUN

Hello friends,
I have a Cisco Blade and would like to boot OVM server from an iSCSI lun. I create a LUN from a SAN and presented the lun to the blade. When the server boots up, it sees the iSCSI lun just fine but when I tried to install OVM server 3.2.1, it did not detect that LUN. I tried to install Oracle Linux 6.3 and it sees the LUN ok. Is there a way to make OVM server to see that LUN.
thanks,
TD

I have done to many oel and ovs install lately such that they are blurring together...
On the OVM 3.2.1 install watch closely for a place to add support for non local storage. I remember seeing a small prompt in some of the installs but it may have been from some of the OEL installs (I have also been doing OEL 4, 5, & 6) & not OVM.
Sorry I can't remember right now. If I get a moment and try to run the install process I will and report back if no one else does.

Server 2012 Failover Cluster No Disks available / iSCSI

Hi All,
I am testing out the Failover Clustering on Windows Server 2012 with hopes of winding up with a clustered File Server once I am done.
I am starting with a single node in the cluster for testing purposes; I have connected to this cluster a single iSCSI LUN that is 100GB in size.
When I right click on Storage -> Disks and then click 'Add Disk', I get No disks suitable for cluster disks were found.
I get this, even if I add a second server to the cluster, and connect it to the iSCSI drive as well.
Any ideas?

For testing purpose you'd better spawn a set of VMs on a single physical Hyper-V host and use shared VHDX as a back clusterd storage. That would be both much easier and much faster then what you do. + it would be trivial move one of the VMs to another physical
host, shared VHDX to CSV on a shared storage and go from Test & Development to production :) See:

After delete iSCSI LUN vacant space does not become available

px12-400r, one pool on RAID10 (5,42TB).
Pool divided into 4 iSCSI LUN (2TB+2TB+1TB+0,42TB).
After deleteting one of them (on 2TB), this vacant space in tab "System Status" (over Web Interface) shown in the diagram as the free and "Amount of available space" on Status Bar 2TB (on Device Home Page over Web Interface),
but in tab "Disk Management" shows "Allocated/Available" - "5,42TB/0B" , and new volume or iSCSI LUN can not be added ("In any storage pool does not have enough space to add an iSCSI drive"
Storage in AD. Deleting iSCSI LUN over Web Interface under AD user with storage admin rights.
Rebooting storage did not help. What to do? How to return control of this free disk space?

Hello gusev67
To be certain that the iSCSI LUN was actually delete, please try this alternate method to check if the LUN is present and if so, deleted.
Go to Drive Management and click on the "volumes" section of your storage pool
Navigate to the iSCSI LUN that should have been deleted/removed
If it is present there, please click on the iSCSI LUN name to show the iSCSI information overview for the LUN, there click on the "delete" option.
If that does not seem to resolve the issue I recommend contacting LenovoEMC support regarding the problem.

Can not attach older iSCSI lun to repository

I am a current Virtual Iron user and have set up OVM to replace my aging system. I have everything set up on some new hardware and up to a point where I want to set up some VMs.
I have an older VM under Virtual Iron I am no longer using, so I thought this would be a good test subject.
I assigned both my OVM servers to the volume in my iSCSI san.
The SAN and volume show correctly within the storage tab.
I have rescanned for physical disks on each server and found the volume.
I can not create a VM just using the physical disk....I wants me to use a repository...
Ok, so I tried to create a repository using the existing volume that contains my server....no go...get this error

Looks like it will not use the volume because something is on it.
In Virtual Iron, I could use a virtual storage (repository), local disks, or iSCSI luns for my VMs.
So how am I to use my older server within OVM?

Ok. Found that someone else was having similar problems....

P2v conversion of sap ecc6 host w/ ISCSI Lun

Hello, I am looking for some feedback here please.
Background:
We have an Physical SAP Host that has ISCSI LUNs (volumes) attached with are formatted as NTFS file system. These are then presented to the OS as drive letters L:\ (Logs) and D:\ (Database) and M:\ (Backups).
We want to virtualize the entire machine and create a virtual machine on ESX Virtual Infrastructure 3. We have an EMC AX4 SAN.
The question is how to do it?
There appear to be two ways:
1. The first way and perhaps the easier way would be to stop SAP, stop the Database and log off the ISCSI adapters from the OS. Then virtualize the physical machine (P2V) with only the C:\ drive. When the machine comes up as a virtual host, it should reattach directly to the existing LUNs through its internal configuration and attach to the existing LUN. We may have to fiddle around with the drive letters to get them to be as previously L:\ D:\ and M:\ but essentially there is not really anything else to do. The internal EMC Powerpath should still be working properly. The ESX Host is already connected and configured to have one physical adapter on the iSCSI VLAN; thus, there should be no additional configuration as long as the VM sees the same network.
2. The second way would be to perform the entire P2V migration and create a brand new gigantic LUN on the SAN and virtualize the entire physical host including all the attached drives. The disadvantages here would be that the entire machine would be on one gigantic LUN and each Drive Letter would be a different file. (I believe).
To complicate things we also have a Cluster with three ESX Hosts. VMotion between Hosts would be no issue under either solution.
I would like to get feedback on how to proceed and hear about any pros/cons and or any success or failure stories.
Thank you,
Pete

Hi Nadeem
Save your init<SID>.ora.
You can try to set processes and sessions parameters in the init<sid>.ora to the following value :
processes = 800
sessions =1600
- Stop your instance
- Stop your DB
- Recreate the spfile
- Start your DB
- Start your instance
If the issue does not solve the problem, you return back.
Otherwise, when you start your instance is that the processes dw.sap <SID> _DVEBMGSXX starts then dies or they do not start?
Best regards.

Add iSCSI LUN to Multiple Hyper-V Cluster Hosts?

Is there a way to connect multiple Hyper-V hosts to a CSV LUN without manually logging into each and opening the iSCSI Initiator GUI?

Is there a way to connect multiple Hyper-V hosts to a CSV LUN without manually logging into each and opening the iSCSI Initiator GUI?
Here's a good step-by-step guide on how to do everything you want using just PowerShell. Please see:
Configuring iSCSI storage for a Hyper-V Cluster
http://www.hypervrockstar.com/qs-buildingahypervcluster_part3/
This part is should be of a particular interest of yours. See:
Connect Nodes to iSCSI Target
Once the target is created and configured, we need to attach the iSCSI initiator in each node to the storage. We will use MPIO to
ensure best performance and availability of storage. When we enable the MS
DSM to claim all iSCSI LUNs we must reboot the node for the setting to take affect. MPIO is utilized by creating a persistent connection to the target for each data NIC on the target server and from all iSCSI initiator NICs on our hyper-v
server. Because our hyper-v servers are using converged networking, we only have 1 iSCSI NIC. In our example resiliency is provided by the LBFO team we created in the last video.

New files and folders on a Linux client mounting a Windows 2012 Server for NFS share do not inherit Owner and Group when SetGID bit set

Problem statement
When I mount a Windows NFS service file share using UUUA and set the Owner and Group, and set the SetGID bit on the parent folder in a hierarchy. New Files and folders inside and underneath the parent folder do not inherit the Owner and Group permissions
of the parent.
I am given to understand from this Microsoft KnowledgeBase article (http://support.microsoft.com/kb/951716/en-gb) the problem is due to the Windows implmentation of NFS Services not supporting the Solaris SystemV or BSD grpid "Semantics"
However the article says the same functionality can acheived by using ACE Inheritance in conjunction with changing the Registry setting for "KeepInheritance" to enable Inheritance propagation of the Permissions by the Windows NFS Services.
1. The Precise location of the "KeepInheritance" DWORD key appears to have "moved" in Windows Server 2012 from a Services path to a Software path, is this documented somewhere? And after enabling it, (or creating it in the previous
location) the feature seems non-functional. Is there a method to file a Bug with Microsoft for this Feature?
2. All of the references on demonstrating how to set an ACE to achieve the same result "currently" either lead to broken links on Microsoft technical websites, or are not explicit they are vague or circumreferential. There are no plain Examples.
Can an Example be provided?
3. Is UUUA compatible with the method of setting ACE to acheive this result, or must the Linux client mount be "Mapped" using an Authentication source. And could that be with the new Flat File passwd and group files in c:\windows\system32\drivers\etc
and is there an Example available.

I'm making some "major" progress on this problem.
1. Apparently the "semantics" issue to honor SGID or grpid in NFS on the server side or the client side has been debated for some time. It also existed as of 2009 between Solaris nfs server and Linux nfs clients. The Linux community defaulted to declaring
it a "Server" side issue to avoid "Race" conditions between simultaneous access users and the local file system daemons. The client would have to "check" for the SGID and reformulate its CREATE request to specify the Secondary group it would have to "notice"
by which time it could have changed on the server. SUN declined to fix it.. even though there were reports it did not behave the same between nfs3 vs nfs4 daemons.. which might be because nfs4 servers have local ACL or ACE entries to process.. and a new local/nfs
"inheritance" scheme to worry about honoring.. that could place it in conflict with remote access.. and push the responsibility "outwards" to the nfs client.. introducing a race condition, necessitating "locking" semantics.
This article covers that discovery and no resolution - http://thr3ads.net/zfs-discuss/2009/10/569334-CR6894234-improved-sgid-directory-compatibility-with-non-Solaris-NFS-clients
2. A much Older Microsoft Knowledge Based article had explicit examples of using Windows ACEs and Inheritance to "mitigate" the issue.. basically the nfs client "cannot" update an ACE to make it "Inheritable" [-but-] a Windows side Admin or Windows User
[-can-] update or promote an existing ACE to "Inheritable"
Here are the pertinent statements -
"In Windows Services for UNIX 2.3, you can use the KeepInheritance registry value to set inheritable ACEs and to make sure that these ACEs apply to newly created files and folders on NFS shares."
"Note About the Permissions That Are Set by NFS Clients
The KeepInheritance option only applies ACEs that have inheritance enabled. Any permissions that are set by an NFS client will
only apply to that file or folder, so the resulting ACEs created by an NFS client will
not have inheritance set."
"So
If you want a folder's permissions to be inherited to new subfolders and files, you must set its permissions from the Windows NFS server because the permissions that are set by NFS clients only apply to the folder itself."

3. I have set up a Windows 2008r2 NFS server and mounted it with a Redhat Enteprise Linux 5 release 10 x86_64 server [Oct 31, 2013] and so far this does appear to be the case.
4. In order to mount and then switch user to a non-root user to create subdirectories and files, I had to mount the NFS share (after enabling Anonymous AUTH_SYS mapping) this is not a good thing, but it was because I have been using UUUA - Unmapped Unix
User Access Mapping, which makes no attempt to "map" a Unix UID/GID set by the NFS client to a Windows User account.
To verify the Inheritance of additional ACEs on new subdirectories and files created by a non-root Unix user, on the Windows NFS server I used the right click properties, security tab context menu, then Advanced to list all the ACEs and looked at the far
Column reflecting if it applied to [This folder only, or This folder and Subdirectories, or This folder and subdirectories and files]
5. All new Subdirectories and files createdby the non-root user had a [Non-Inheritance] ACE created for them.
6. I turned a [Non-Inheritance] ACE into an [Inheritance] ACE by selecting it then clicking [Edit] and using the Drop down to select [This folder, subdirs and files] then I went back to the NFS client and created more subdirs and files. Then back to the
Windows NFS server and checked the new subdirs and folders and they did Inherit the Windows NFS server ACE! - However the UID/GID of the subdirs and folders remained unchanged, they did not reflect the new "Effective" ownership or group membership.
7. I "believe" because I was using UUUA and working "behind" the UID/GID presentation layer for the NFS client, it did not update that presentation layer. It might do that "if" I were using a Mapping mechanism and mapped UID/GID to Windows User SIDs and
Group SIDs. Windows 2008r2 no longer has a "simple" Mapping server, it does not accept flat text files and requires a Schema extension to Active Directory just to MAP a windows account to a UID/GID.. a lot of overhead. Windows Server 2012 accepts flat text
files like /etc/passwd and /etc/group to perform this function and is next on my list of things to see if that will update the UID/GID based on the Windows ACE entries. Since the Local ACE take precedence "over" Inherited ACEs there could be a problem. The
Inheritance appears to be intended [only] to retain Administrative rights over user created subdirs and files by adding an additional ACE at the time of creation.
8. I did verify from the NFS client side in Linux that "Even though" the UID/GID seem to reflect the local non-root user should not have the ability to traverse or create new files, the "phantom" NFS Server ACEs are in place and do permit the function..
reconciling the "view" with "reality" appears problematic, unless the User Mapping will update "effective" rights and ownership in the "view"

G5 as a Server for Online Gaming?

I am curious as to if a G5 can be used for a Server for Online Gaming prior to my going out and purchasing one. I am new to Apple computers and would like to know if i bought the Full Upgraded version.. would the game work and be able to handle the amount of gamers that play the game.. (currently approximately 200-300 players at any given time)
thank you for the assistance...

Yes it certainly can but which online games have
server versions that run on a G5?
Maybe i didnt explain it better... I want to use my G5 to be the HOST server for the online game.. is "this" possible??

How to change and save a new file in Edge web Lumira server for Team ?

Hi Lumira folks,
I've installed SAP Lumira 1.0, Edge edition and View a sample 'Dairy Wholesaler-Sample"
I'd like to change it and save as new file, but "Save" button is disabled and when I put my mouse over the button,
it says "Save Option is disabled in this version".
Is there any idae how to change and save as a new file in Lumira Edge ?
Many Thanks.
JH

I've just found the reason as below.
http://scn.sap.com/community/lumira/blog/2015/03/20/lumira-server-for-teams-edge-edition-version-compatibility
The current version of Lumira
server for teams is 1.0. This version uses Lumira 1.22 as its 'engine' as this
was the version of Lumira Desktop that was shipped at the same time.
Hence with the current Lumira
version compatibility; namely that a newer version of the product can open an
older document, but an older version cannot open a newer document, care must be
taken when deploying Lumira server for teams.
Lumira server for teams is only
compatible with Lumira desktop 1.22. If you intend to deploy Lumira server for
teams, ensure your desktop users do not move to a later version of the desktop.
Content created in a later version of Lumira desktop can be uploaded and shared
via Lumira server for teams, but it cannot be viewed or edited online in the
browser.
Ensure desktop users disable the
auto update capabilities in the desktop preferences, and set the update to
none.
