To add fibre-channel LUNs on the fly

I added a new LUN from my SAN and ran "rescan-scsi-bus.sh" on my OVM Server.
After that,
My "fdisk -l" hangs.
At the GUI, I'm able to see the new LUN and somehow its status is locked.
Even though I tried rebooting the OVM Server, it remains locked.
Did I miss any step or did I go through the right step to add a new Fibre Channel LUN dynamically?
Thanks in advance.

Hi Snehangshu,
It's still locked even after running those commands.
When I log into the OVM Server, it displays the following warning message as well.
Warning: making manual modifications in the management domain
might cause inconsistencies between Oracle VM Manager and the server.
Even with another reboot, it didn't make a difference.
I guess the most of people use NAS or iSCSI over FCP with OVM 3?
Thanks.

Add Fibre Channel LUN to Server 2012 R2

I'm having difficulty configuring SAN storage attached to a pair of 2012 R2 hosts. I'm building a two node Hyper-V cluster. Bear in mind this is an operation that I'm very familiar with using VMware. I'm simply trying to get the windows
hosts to see the LUN so that I can configure it as shared disk in the Hyper-V cluster. This is IBM System x3850 storage. The host each have Emulex LPe 12000-M8 HBAs. Also, I'm pretty sure that the disk is visible from the HBAs in the OneCommand
utility. <see below>
I've tried to run the mpclaim -e command and it returns "There is no enterprise storage connected on the system"
What am I not doing? MPIO? I've tried adding a device using the 8x16 rule "IBM 5639 "
I can't find any documentation that explains how to do this in server 2012 R2 ANYWHERE!!!! I'm pulling my hair out and I don't have that much to lose!! :)
Please help!
Thank you,
Roger

Again, this is not a Windows issue. I am not familiar with the IBM utility, so I don't know what that is showing. I just know that critical to accessing Fibre Channel LUNs is that you have your SAN network zoned to allow the WWPN from your
HBA to talk to the WWPN of the Fibre Channel controllers, and then on the controller you need to mask the LUN to expose it to the WWN of your server. If that is not done, Windows will not see anything. Once it is done, Windows sees the disk as it if were a
local disk.
I do see that you have two HBAs, and some of the WWN information seems to be duplicated. Most likely you are trying to configure some form of MPIO. I am assuming that is something provided by the IBM software, but it must be working properly
otherwise, once the zone/mask is correct, you will see each LUN two or more times, depending upon your Fibre configuration.

Hi, we have a G5 Blade server running OS X 10.5.8 with a dual Fibre Channel card. The OS does not read the card and cannot establish connection to the RAID controller. I have tried to move the card to another port with no luck. Ran all the updated softwar

Hi, we have a G5 Blade server running OS X 10.5.8 with adual Fibre Channel card. The OS does not read the card and cannot establishconnection to the RAID controller.
I have tried to move the card to another port with no luck.Ran all the updated software possible. Please can someone advice

Hi,
Was the card previously working in that machine? If it was and you have a G5 tower you could try the card in there. Here is a list of Apple fibre cards and cables which show what's compatible with what. http://support.apple.com/kb/HT1769
The card should appear in the System Profiler under Fibre Channel and PCI Cards.

OVM 3.1.1 Add new Fiber Channel LUN on the go

Hello everyone,
I've a question regarding Fiber Channel LUNs. I need to present a new Fiber Channel LUN to my 2 production servers and I would ask what's the best procedure to do this.
Usually I turn off servers present FCP LUN then turn servers on, but what if I can't poweroff servers?? There's a way to present FCP LUNs without powering off servers??
Thanks in advance. ;)

I have already met this problem.
In the Manager, you can right-click a VM Server and select "re-scan physical disks". That sounds like it would work, right?
Well, it has NEVER worked for me. Maybe someone can tell me what I'm doing wrong.
But what DOES work is:
Present the LUN to all servers.
Go to one of the servers, log in as root, and run: rescan-scsi-bus.sh
This makes the new LUN known to the server.
Then go back to the Manger, and do the "rescan physical disks" thing. This gime the new LUN will appear, and it even appears to ALL servers in the cluster. You're done. (It seems like sometimes the LUN will appear in the GUI after running rescan-scsi-bus.sh, without doing anything. But I'm not sure.)

What is the maximum number of Fibre Channel LUNS visibile in Solaris 11.2

I have SPARC T4-4's with 4 emulex HBA ports. What is the maximum number of LUNS I can have exported to that server?

Hi Jim,
MOS doc 1018739.1 describes maximum Solaris SCSI and FC targets, LUNs, and device instances.
The FC limit for maximum LUNs is either 65535 or unlimited.
Thanks, Cindy

Creating buttons on the fly and setting button properties

If I have a view and want to add buttons to it "on the fly" from values in an array, is that something straightforward to do?
I have an array of UIImageVIew objects and would like to create buttons from them (showing the image on the buttons) and associate those buttons with a method in my implementation file. That would be a lot more general and flexible than creating the buttons in the Interface Builder I would imagine.
And one more question - can I freely set button properties while doing that? Or in Objective-C can I only set properties that are already pre-defined for that class?
Thanks!
doug

Thanks for your reply.
That.... works! Thanks!
And I can generate the button and click on it and it calls my other method and that works too. Cool!
The syntax is still very mysterious to me, but I suppose eventually I'll understand what it all means.
Breaking it down to see what it means:
[button1 addTarget:self action:@selector(selectedHandler1:) forControlEvents:UIControlEventTouchUpInside];
* button1 is the object I created (I'm going to try to do this in a loop next.)
* addTarget is a message I am sending to button1 and the content of the message is "self", which refers to - this button? I'm not sure why such a message would be necessary.
* action is another message sent to button1 and the contents of that message are a little harder to parse. I see the result, and can mimic the syntax now that I've seen it, but I don't really understand what the @ is for, or the : after the method name or why this wouldn't just be "action: selectedHandler". I'm sure the language designers have a logical reason for all that, but I don't quite "grok" those extra symbols yet.
* forControlEvents is another message sent to button1 and the event message itself is clear in its meaning.
Anyway, that is working and I can refer more to the UIButton class reference now and try to set more stuff, like position it better, etc.
Thanks very much!

Fibre Channel Jumbo Frames - UCS

I was wondering if it's actually possible to have Jumbo Fibre Channel Frames running on a UCS?
I've read these two articles which provide some excellent information on implementing Jumbo Frames and Fibre Channel Jumbo Frames:
http://datacenteroverlords.com/2013/04/01/jumbo-fc-frames/
http://www.ccierants.com/2013/10/ccie-dc-definitive-jumbo-frames.html
Everything within the SAN I'm administrating has the ability to set the MTU up to 9036 except for the UCS. For example on the NetApp gear I can set the MTU per interface, on the Cisco MDS I can set the MTU per vsan. However in the UCS manager when I go to QoS System Class, the option to set the MTU for Fibre Channel is greyed out and it doesnt look like there's anyway to override the preset frame size. I can set the MTU of Best Effort however my understanding is Fibre Channel traffic within the UCS will use the Fibre Channel system class.
Furthermore I noticed I can set the Maximum Data Field Size on the vHBA's within the UCS manager however my understanding is the maximum this can go up to is 2048.

Xserve RAID Fibre Channel Lights pegged until disk activity

We are having some issues with an Xserve RAID connected to a G5 Xserve running 10.4.8 Server. The Fibre Channel lights on the front are constantly maxed out, but whenever the disk are active the lights die down only to peg again when activity stops. Needless to say, we are having SEVERE access speed issues. Any ideas?

This can happen in a protected RAID set (i.e. RAID 5) if a single raid member drive pops offline and back on again, since the RAID set has to re-build itself from the parity data in that case.
It also happens after creating a RAID 5 volume, as the creation usually takes a few days (assuming you used the 'RAID Now' option), and so you'll see the blue lights.
It also makes sense that the blue light 'spiking' would drop when you do a read/write, as the initialization process has to pause to handle the disk activity.
Are either of these the case?

How to obtain target WWN for a LUN On Windows 2012 R2 Hyper-V with Fibre Channel SAN

I have a large collection of Hyper-V hosts for which I would like to retrieve the target WNN and LUN ID for the LUNs visible on each host. By target WWN I mean the storage array's WWN.
I have tried using the root\wmi namespace to retrieve MS_SMHBA_PORT_LUN instances, but I get 0 instances back.
I get instances of MSFC_FibrePortHBAAttributes back, but those only tell me the local host's HBA WWN, not the target information.
This information must be stored somewhere, because you can't access the LUN without it, I hope there is a way to retrieve it. Is there? Or is it write only during LUN setup?

Hi,

I am missing the add objects section from the fly out menu in Photoshop CS6. 3d workspace

I am missing the "add objects" section from the fly out menu in Photoshop CS6. I am in the 3D workspace of Photoshop. "Scene" is highlighted and I have clicked on the little fly out menu in the upper right hand corner of that panel. The whole section that should contain, Add objects, delete objects, duplicate objects, all the way through reverse order is missing. The add lights section above and render section below it is there. I am not new to Photoshop, but I am new to the 3D section of Photoshops work space.
I do know about creating a new layer in the layers tab and merging the objects together trick. But I kind of would like for the program to work correctly as I am sure that doing it that way will cause some sort of problems later in the work process.
Below are the specs of my system.

I am actually running windows 8. So I am not sure why it is saying windows NT. Anyway...
Photoshop says that my software is up to date. I use Photoshop daily and everything else works just fine. I have looked through this forum and there is someone else who had the same issue as me but their question was not given a solution. So that is why I choose to post it again.
Any help will be great. Thank you!
Mark.

I've made tests with four different 3rd party tools: OpenGL Extension Viewer, GPU Caps Viewer, Compute4Cash OpenCL Diagnostic Tool and Mudlord's Glide3x wrapper tester. All those tools report no problems with my video card driver and OpenGL/CL.
I have contacted nVidia and based on reports from the tools and visual tests from GPU Caps Viewer nVidia support doesn't see a problem with my driver.
I found sniffer_gpu.exe which according to Adobe Help pages is a kind of diagnostic tool and determines whether Photoshop uses the graphic card OpenCL or not. Here is the output:
Device: 00000000002B1BE8 has video RAM(MB): 1023
Vendor string: NVIDIA Corporation
Renderer string: GeForce GTX 650/PCIe/SSE2
Version string: 3.0.0
OpenGL version as determined by Extensionator...
OpenGL Version 3.0
Has NPOT support: TRUE
Has Framebuffer Object Extension support: TRUE
OpenGL ok
OpenCL ok, version=1.1 CUDA 4.2.1
Return code: 3
From Adobe GPU Sniffer tool, it looks OK.
On the other hand, I have your word that there is no problem with Photoshop not recognizing OpenCL for my card and that nVidia driver has problems. Can you justify this somehow? Perhaps you could provide more details on technical level, or another utility to run and extract details, to at least identify the problem Photoshop has and hopefully solve it on either side.
P.S. During tests there were two things which I noticed, but they are probably not related to the issue:
1. One tool reports the lack of Windows registry key SOFTWARE/Microsoft/Windows (NT)/CurrentVersion/OpenGLDrivers. But according to your previous statement, Photoshop only uses OS calls, no registry and according to nVidia, this key is not used in Windows 7.
2. During some tests GPU Caps Viewer reports that "OpenCL CPU not supported on the selected platform". This is not complaining about GPU, only about CPU. But Photoshop is complaining about GPU, so it shouldn't be relevant.

Cs6 , how can i add a anchor point in the curve in the channel Red or Green?

Hi
how can i add an anchor point in the curve in the Channel R / G and B?
in cs5 , with ctrl + click i was able to click on the image and add an anchor point in the curve channel RGB
and with shift +ctrl + click i was able to click on the image and add an anchor poing in the channel Red , 1 in the channel Green and 1 in the channel blue
i know cs6 doesn't have any more ctrl+mouse click , there is the targeted adjustamanent tool
i can do it with ctrl+m and call the curve
but i can't do it with curve adjustament tool
is there a way to add a anchor point in each channel red , green and blue (like the prev photoshop)?
thanks

thanks that's correct! thanks
but it's not 100% correct
to add a multiple points in rgb shift+click doesn't work!
from adobe
Keyboard shortcuts: Curves
You can use these keyboard shortcuts for Curves:
To set a point on the curve for the selected color in each color component channel (but not in the composite channel), Shift+Ctrl-click (Windows) or Shift+Command-click (Mac OS) in the image.
To select multiple points, Shift-click points on the curve. Selected points are filled with black.
To deselect all points on the curve, click in the grid, or press Ctrl‑D (Windows) or Command-D (Mac OS).
To select the next higher point on the curve, press the plus key; to select the next lowest, press the minus key.
To move selected points on the curve, press the arrow keys.
(Curves dialog box) To set a point on the curve for the current channel, Ctrl-click (Windows) or Command-click (Mac OS) in the image.
If you’re instead using the Curves adjustment, simply click in the image with the On-image adjustment tool .

Can't add layer markers on the fly with Mac laptop

I've been trying to figure this out for hours now!!! I'm on a Mac Intel Core 2 Duo laptop running 10.5.6. I'm using After Effects CS3 Professional. All I want to do is RAM preview an audio file from inside a composition, and add layer markers on the fly. Apparently this is easy with a desktop using the numeric keypad. I remapped the shorcut in the Preferences text file so that "Add Marker" is now F12 - nice and easy! (and no, it's not conflicting with the the OS Dashboard shortcut - I turned that off). In any case, I tried a number of others as well. The problem is, no matter what the shortcut, when I try adding the layer marker with the shortcut the file stops playing! So annoying! I want to add a number of layer markers timed to the beat, but as soon as I do the damned RAM preview stops! I can't mark key points in the composition!! Any help would be MUCH appreciated...
- Bryan

Hi there
I hope it's ok to continue this old thread - as I'm having a very similar problem, but with a PC laptop
I want to re-map the numeric-keypad-star key so I can hit markers on the fly while ram previewing (my laptop has no numeric keypad), but I don't know what the shortcut is called in order to be able to find it to re-map it!! Can anyone tell me what the shortcut is called?
Also from this thread it seems even if I do re-map it may not work - can anyone tell me whether this will be the case for a PC? I'm using a Dell Studio 1557 Core i7 with Win7 64bit, running After Effects CS4
All advice appreciated
Thanks

How to add Prelisten channels to the Environment?

I think I deleted my Prelisten channels, and I can't figure out how to add a channel strip for Prelisten to the mixer or to the environment. I'd never used the Prelisten function yet since upgrading to LP 8; thus, I'm not sure what I did, but I think I deleted Prelisten somehow while cleaning up my last session.
Any help would be great. Thanks in advance!

OK. I think I just figured it out. I just added another stereo pair, and the new pair is working as Prelisten. Sweet.
I'd deleted every unused channel strip, and in order for Prelisten to work, your song has to have at least one additional stereo channel strip, apparently.
