Configure iSCSI multipath in OVM 3.1.1 with storage plug-in not possible ?

I have a configuration with 4 iSCSI paths to storage system. All is working fine if the discover and login
process was performed manual. Multipath is working well with 4 paths.

I want to configure iSCSI multipath in OVM manager using specific storage plug-in.
I proceed “Discover SAN Server” with following parameter:
Name: Storage-Name
Storage Type: iSCSI Storage Server
Storage Plug-in: Fujitsu ETERNUS
Admin Host: IP-Addr. of storage system
Admin Username: user name to access storage system
Admin Password: password
Access Host (IP) Address: 192.168.10.1
After this configuration I see my storage system and assigned physical volumes to an access group.
Now the volumes are available on the OVM storage server, >>>> but I lost the multipath functionality <<<<<.
# multipath -ll
3600000e00d1000000010000000120000 dm-1 FUJITSU,ETERNUS_DX400
size=30G features='1 queue_if_no_path' hwhandler='0' wp=rw
`-+- policy='round-robin 0' prio=50 status=active
`- 33:0:0:1 sdd 8:48 active ready running
The reason for this behavior is that only one Access Host (IP) Address can be specified.
With this IP address a session was established … but only 1 session and not 4 !!
How can I specify the remaining 3 paths to have proper multipath functionality?
I know that Citrix XenServer accepts more Access Host (IP) Addresses,
e.g. 192.168.10.1,192.168.10.2,192.168.20.1,192.168.20.2
Thanks for help.

@user12273962
Yes, you are right. The storage plug-in is for management of the storage within OVM.
This is working well, but I'm still missing the multipath fuctionality. This storage plug-in is not responisble
for establish the multipath, but OVM should take care of this.
@budachst
Yes, OVM did only open one session and loggin only to one target, because only one Access Host (IP) Address: 192.168.10.1
can be specified.
# iscsiadm -m session
tcp: [21] 192.168.10.1:3260,25 iqn.2000-09.com.fujitsu:storage-system.eternus-dx400:CM0CA3P0
In my point of view it is not possible to configure the remaining targets, so this is a design problem.
Any new inputs and informations are welcome.

ESX 5.1 and iSCSI multipathing

Hello.
I have a problem in configuring vSphere Cluster with iSCSI multipathing.
Host in cluster have four physical interfaces. Host have four vmk interfaces for iSCSI, which mapped to individual physical interface.
Storage is IBM Storwize 3700 with four configured targets (10.78.2.2 - 10.78.2.5).
Why I see only 4 paths to storage? I think there should be 16, I am right? (4if from storage * 4if from host).
Rescan HBA not resolve this problem.
P.S. All paths on storage work properly on another host not in cluster.

Actually found the reference , its in the firmware upgrade guide itself:
All connectivity may be lost during firmware upgrades if you have configured both Enable Failover on one
or more vNICs and you have also configured NIC teaming/bonding at the host operating system level. Please
design for availability by using one or the other method, but never both.
Is this still valid? Whats the setting to be done on ESX nic teaming if we wanna use Enable failover on UCS?

OVM 3.3.1: NFS storage is not available during repository creation

Hi, I have OVM Manager running on a separate machines managing 3 servers running OVM server in a server pool. One of the server also exports a NFS share that all other machines are able to mount and read/write to. I want to use this NFS share to create a OVM repository but so far unable to get it to work.
From this first screen shot we can see that the NFS file system was successfully added under storage tab and refreshed.
https://www.dropbox.com/s/fyscj2oynud542k/Screenshot%202014-10-11%2013.40.00.png?dl=0
But its is not available when adding a repository as shown below. What can I did to make it show up here.
https://www.dropbox.com/s/id1eey08cdbajsg/Screenshot%202014-10-11%2013.40.19.png?dl=0
No luck with CLI either. Any thoughts?

Actually, OVM, as is with all virtualization servers, is usually only the head on a comprehensive infrastructure. OVM seems quite easy from the start, but I'd suggest, that you at least skim trough the admin manual, to get some understanding of the conecpts behind it. OVS thus usually only provides the CPU horse power, but not the storage, unless you only want to setup a single-server setup. If you plan on having a real multi-server setup, then you will need shared storage.
The shared storage for the server pool, as well as the storage repository can be served from the same NFS server without issues. If you want to have a little testbed, then NFS is for you. It lacks some features that OCFS2 benefits from, like thin provisioning, reflinks and sparse files.
If you want to remove the NFS storage, then you'll need to remove any remainders of any OVM object, like storage repositories or server pool filesystems. Unpresent and storage repo and delete it afterwards… Also, I hope that you didn't create the NFS export directly on the root of the drive, since OVM wants to remove any file on the NFS export and on any root of ony volume there's the lost-found folder, which OVM, naturally, can't remove. Getting rid of such a storage repo can be a bit daunting…

How do I configure my Airport Extreme to see the printer I have plugged into the USB port?

How do I configure my Airport Extreme to see the printer I have plugged into the USB port?

OK. The 6.0 version no longer has a printer configuration that I could find. You might try Printer Sharing in the Sharing preferences.
I would also check the printer's user manual for help with the setup, and that failing check the manufacturer's website and/or tech support.

How can I configure the save page mode (to save DEFAULT WITH OR WITHOUT images and other dependencies in a folder)?

I like it that I can save webpages with or without dependencies in a separated folder. And its implementation in Firefox (e.g. it remembers how I saved something before, and that way becomes the default) can also be good sometimes. But usually it is not.
Usually I want to save pages as HTML-only. Sometimes, but only sometimes I have to save a page as a whole (I don't know the name of the feature). But after I save something with dependencies, I often forget that, and don't care about this option. Firefox, however, doesn't forget it, and saves thousands of unimportant images, until I notice it and switch it off again.
This is not good.
I tried Google Chrome, which simply don't remember how I saves something before, and always select the complete page option for default. It is exactly the opposite of the perfect solution (in my opinion). The best would be if the browser would save everything as HTML only, if I don't change it. Or it would be even better if I could configure it manually (turn this remembering feature on/off).
This is not a beginner's problem, so it would be good if only a config option solved this. I imagine that already exists a config option for this, but I could not find it. I found only the "browser.download.save_converter_index" option, which depends on how I used it last time.
Is there a config option for this? Or should I report this in the Firefox brainstorm page?
Thank you for your time
D. J. S.

That choice is remembered in the Integer pref <b>browser.download.save_converter_index</b>
0: Web Page, complete (default)
1: Web Page, HTML only
2: Text files
If you want to reset that choice to HTML only on every start of Firefox then you can use this line in the file [http://kb.mozillazine.org/user.js_file user.js]
<pre><nowiki>user_pref("browser.download.save_converter_index", 1);
</nowiki></pre>

JBO-33001: Configuration file /oracle/apps/crmCommon/activities/activityManagementService/applicationModule/common/bc4j.xcfg is not found in the classpath.

I am trying to consume a base model which is available in the Customer.jws (AppCmmnCompActivitiesPublicModelActivityManagement) to my Mobile UI project available in Sales.jws (SalesMobilePublicUi). We have added proper Databindings.cpx entry for accessing the applicationModule present in the model.
On deploying the sales mobile app, I get the following ConfigException:
JBO-33001: Configuration file /oracle/apps/crmCommon/activities/activityManagementService/applicationModule/common/bc4j.xcfg is not found in the classpath.
The bc4j.xcfg mentioned in the above path actually contains the entry. On checking about this issue, I found out that the prominent solution would be model project should be added as Dependencies to the UI project. But the UI is in different workspace (Sales.jws) and so the list of dependencies shown are those of this workspace only, whereas the model is present in Customer.jws and it does not come under the dependencies list.
How can this issue be resolved? Please let me know any pointers on solving this issue.

Build an adfLibrary from the model in the Customers.jws and add this adfLibrary to the other ui project. This will get you the dependency.

Configure New TM on a New Macbook pro with retina display Issue

I have bought a new New Macbook pro with retina display laptop (Lion moutain OS)and a new TM (2TB).
I have an internet router with wireless connect.
I plugged TM to the router with an ethernet cable.
Connect my TM to my macbook with an ethernet cable.(at this point I still cannot see TM on my Mac)
then I choose Time capsule from WiFi as shown below:
Then the airport utility (version 6.1) opened and start configuring TM but it gives an expected error when it is starting to join the TM!!!!
I have reset the TM several time but with no hope.
PS: I can configure the same TM on a normal laptop with windows 7 installed and Airport utility 5.6
I am struggling on this issue for weeks and I cannot yous TM on my macbook pro.
Help please.

Time Capsule .. TC is the hardware box you bought.. Time Machine is the software you use in the Mac computer.. so what you generally refer to as TM is really TC.. !!
I can configure the same TM on a normal laptop with windows 7 installed and Airport utility 5.6
That is great.. you do not need to setup the Time Capsule at all then. It is already setup.. forget using 6.1 utility.. it is useless toy version.
Just use it.. open Time Machine and see if you can connect to the TC drive to do backup.. and to the wireless.
From your statements..
Connect my TM to my macbook with an ethernet cable.(at this point I still cannot see TM on my Mac)
You are trying to connect with both wireless and ethernet at once.. This can mess things up. choose wireless or ethernet.. not both.
If you keep running into issues.. reset the TC.. I know yet again.
Set it up using SMB names.. for both the TC itself and wireless.
Then lock the wireless channel for 2.4ghz.. use channel 1, 6, or 11 (13 in europe) and see how it goes.

I believe you are trying use Sales order for services....and you have created material in services if I am not wrong.
Again sticking to basic rules, you can configure only materials with type KMAT. Further for services, I believe there is a concept called milestone billing...which I am not sure about.

Hello Marek,
I suppose you are not planning to do any kinds of advanced config using several VLANs and multiple SSIDs so let's just make your configuration simple and working.
In short, you need to remove all references to VLAN 1 and to any subinterfaces possibly related to the VLAN 1. This means in particular (follow these steps in sequence):
Remove the Dot11Radio0.1 subinterface entirely
In the Dot11Radio0 section, remove the encryption vlan 1 mode ciphers tkip command
In the dot11 ssid ciscowifi section, remove the vlan 1 command
After performing these steps, make sure that the ssid ciscowifi and encryption mode commands are still present in the Dot11Radio0 configuration, and if not, reenter them.
Best regards,
Peter

2. Message for the configuration check.
Please guide me where i did the mistake? and suggest me how to correct this error message, without doing the changes in message controls.

JK,
My guess is that you are using Configuration Control.
If so, then have a look at these transactions:
