Cisco fibre channel domain manager "fast start" feature

Hi there:
I'm trying to understand the
cisco fibre channel domain manager "fast start" feature
but I can't
Manual say:
About Domain Manager Fast Restart
As of Cisco MDS SAN-OS Release 3.0(2), when a principal link fails, the domain manager must select a new principal link. By default, the domain manager starts a build fabric (BF) phase, followed by a principal switch selection phase. Both of these phases involve all the switches in the VSAN and together take at least 15 seconds to complete. To reduce the time required for the domain manager to select a new principal link, you can enable the domain manager fast restart feature.
When fast restart is enabled and a backup link is available, the domain manager needs only a few milliseconds to select a new principal link to replace the one that failed. Also, the reconfiguration required to select the new principal link only affects the two switches that are directly attached to the failed link, not the entire VSAN. When a backup link is not available, the domain manager reverts to the default behavior and starts a BF phase, followed by a principal switch selection phase. The fast restart feature can be used in any interoperability mode.
Questions:
Those links are not a Port channel, aren't they?
If those links would form a port channel then it is not need the fast restart feature?
In case of there are not a backup link, should be another fabric path and host should conmute because multipath?
Then, there are very specific scenarios where Fast Restart feature apply, aren't they?
Thank you in advance for your comments

Please post "debug ccsip messages".
Based on your debug you are getting "Cause No. 38 - network out of order."
You may want to bind SIP to an interface that the IP address is defined which Lync points to.

OSX 10.5.6 doesn't see Fibre Channel Disk array, neither does Disk Utility

My system is a Power Mac G5 Quad, 6gb Ram, 1Tb internal hard drives, 1Tb external and several portable drives as needed.
The Drive array in question is a Fujitsu GR710 which contains 12 Seagate Cheeta ST336605FC drives which are around 35gb each.
OK, I have been given a Fibre Channel system, that at one time worked with OSX. I had to move it and now it doesn't show up on Disk Utility anymore. I can totally reformat it if possible, but I have to be able to see it first.
System Profiler sees the setup as:

Fiber Channel Preferences shows that a link is established.
Hardware RAID says that there is no hardware present.
I am using the Apple MA900A/G Fibre Channel Card to hook into the Drive array. It is hooked up with both ethernet and fiber optic cables.
I have used an IP scanner to search for the IP of the array and only find one that I can't identify at 224.0.0.251 another scan reports an IP of 0.0.0.0, neither worked when I tried to use Safari to access it.
I have tried several programs to try and get into this array and nothing sees it. All my experts tell me that I will need to use the Terminal program and use command lines to access the drives, but I can't find any information about what to do there. I've been told I need the driver for the array, naturally there isn't a driver for Mac to be had, but there are drivers for solaris, Unix, and windows. The last expert said to use the Unix driver, but I don't know where to put it in the system.
So I need help, Terminal commands to talk to the drive and revive it hopefully, or a system program that will do something similar. None of my diagnostic programs sees the array. The Card came with no software or instructions. Neither did the array. I haven't been able to find any hardware information about the drive from FuJitsu at all, it's too old for them to bother with anymore.
Any help would be greatly appreciated!
Thanks

I have to go with William on this one - if it's shows up over fibre then it should be okay. Have you gotten the admin module to see the device over ether? I have a feeling that is you can get the software to see it you might be able to configure the device into something the computer could mount.
The Promise that way - you can configure the device entire from the web interface and you don't need fibre communication working for any of the configuration of what RAID you want and which disks are attached with what set etc. Once the RAIDs are configured into volumes then the Xserve sees they exist and you can use Disk Utility to format them. If you don't need fibre communication I don't see how SCSI drivers would matter over ethernet. But maybe the box is a strange beast - odder things have been made.
Barring that - can you attach the device to an older machine with the drivers and configure the device into raw volumes and then an HFS+ (or whatever you want) system? If you did that and then switched the box back to Xserve it should be able to pick up the configured volumes drivers or no.

Cisco Unified CCX Node Manager service terminated unexpectedly

"Windows must now restart because the Cisco Unified CCX Node Manager service terminated unexpectedly."
After I installed my CCX os and software. The os reminded me like above. I guessed I need to upgrade the patch of my OS. And I also installed McAfee ver 8.5i at my OS. But that doesn't work. I noticed that the status of cisco unified ccx node manager was starting.

On a new install, this can occur if you start patching the OS before you get UCCX installed. This is especially a problem in an HA environment. Some of the patches set values to things they should not be if they are applied before the software is installed.
When installing UCCX on a new system, you should build the OS on the box (DO NOT PATCH at this time), Install the UCCX software and integrate with CCM, get your second server (if you are doing HA) on line with OS and UCCX and integrated. Once all the above are done, then you can start installing OS patches and UCCX patches.
You should NEVER start installing things like AV software before you have the system completely up and working. If you do, and they cause issues, you cannot tell if it's a system issue, or something caused by your a/v software.

Cisco TrustSec Fibre Channel Link Encryption performance?

Hello,
could anybody provide me some more details about Cisco TrustSec Fibre Channel Link Encryption? We are thinking to invest in this feature. Can I really use all 32 FC Ports @ 8Gbit wire speed on the 3Gen Cards? Have somebody used this feature already?
Many Thanks in advanced!

In my experience the auto connect never works properly with certain vendor products. Try hard setting your link speed, i.e. 2G or 4G depending on your HBA capabilities and the target device.

How to using Virtual fibre channel feature in IC 3.5?

Hi ,guys ,i have noticed that microsoft released IC 3.5 to support virtual fibre channel in redhat and centos linux.
the links are:
http://technet.microsoft.com/en-us/library/dn531026.aspx
http://blogs.technet.com/b/virtualization/archive/2014/01/02/linux-integration-services-3-5-announcement.aspx
in these links above ,notes 2 says:
While using virtual fibre channel devices, ensure that logical unit number 0 (LUN 0) has been populated. If LUN 0 has not been populated, a Linux virtual machine might not be able to mount fibre channel devices natively.
but I do not understand how to ensure logical unit number 0 has been populated ,anyone who have tested such new features please share your expirence , thank you very much.

The same issues as yours,no HBA card can be seen
I have tried the command here to list hyper-v virutal fiber channel card in oracle linux 6.5 ,but no luck,and EMC powerpath does not support UEK r3 which was installed default on OL 6.5 X64,I will try Oracle linux 6.3 with IC 3.5

Fast Start Failover has broken my Logical Standby and Flashback has not helped

I have a primary ( PRIMARYP ), a physical standby ( STANDBYP ) and a logical standby ( STANDBYL ).
I configured Fast Start Failover ( with STANDBYP as the target ) and started an Observer. I did a shutdown abort on my primary and the Fast Start Failover did make STANDBYP the primary. I was able to reinstate PRIMARYP as a physical standby.
However when I checked my broker config it gave for STANDBYL
ORA-16795: the standby database needs to be recreated
Strange I though, since I would have expected STANDBYL to survive ok given that the new primary, STANDBYP was a physical standby of PRIMARYP.
Not to worry I thought, I simply will flashback STANDBYL to the beginning of the day and SQL APPLY will reapply all the redo.
This is where the problem begins

VSAN Isolation due to domain manager other side not responding

I am trying to configure VE port between Cisco nexus 7K and 5K switches but the vfc is not operational as VSAN isolation.

Nexus 56128P Fibre Channel Interface

Hi everybody,
I'm installing a Nexus 56128P and I try to configure Fibre Channel native interface on GEM N56-M24UP2Q.
I have configured the ports to be fc interface
slot 2
port 1-24 type fc
Then i have reloaded the module, but no fc interface appeared (and no more ethernet interface 2/x).
I checked the license, i have the FC_FEATURES_PKG installed but "unused".
I guess i missed something, but can't figure out what.
Any idea ?
Julien

see https://supportforums.cisco.com/discussion/12254396/fc-ports-nexus-5548up
After the port type has been changed from Ethernet to FC, the FC port will not be enabled on the switch until FCOE feature is enabled:

After that, we verify that the port type is changed successfully and the FC ports appear on the switch:

Need docs that explain Fibre Channel setup, getting I/O error on 2540 SAN

Sun T5220 Host running Solaris 10 5/09 as management host.
Qlogic 5602 FC Switch
Sun Storagetek 2540 - one controller tray with 9 300G SAS Hitachi drives. Firmware 7.35.x.
Sun branded Qlogic QLE2462 HBAs - PCI express, dual port. 3 in the T5220. qlcxxxx drivers for the HBAs.
Sun Common Array Manager software version 6.5.
I am a long-time Oracle DBA who has the task of setting up a Fibre Channel SAN. I am not a Solaris sysadmin, but have installed and maintained large databases on Solaris boxes where I had access to a competent sysadmin. I am at a classified site and cannot bring out electronic files with logs, configuration info, etc. to upload. Connecting the T5220 is the 1st box of many. This is my first exposure to HBA's, Fibre Channel, and SAN, so everything I know about it I have read in a manual or from a post somewhere. I understand the big picture and I have the SAN configured with 2 storage pools each with 1 volume in them on RAID5 virtual disks. I can see the LUN 0 on the T5220 server when I do a luxadm probe and when I do a format. I formatted one of the volumes successfully. Now I attempt to issue:
newfs /dev/rdsk/device_name_from_output_of_luxadm_probe
I get an immediate I/O error. I could be doing something totally naive or have a larger problem - this is where I get lost and the documentation becomes less detailed.
What would be great is if anyone knows of a detailed writeup that would match what I'm doing or a good off-the-shelf textbook that covers all of this or anything close. I continue to search for something to bridge my lack of knowledge in this area. I am unclear about the initiators and targets beyond the fundamental definitions. I have used the CAM 6.5 software to define the initiators that it discovered. I have mapped the Sun host into a host group also. I do not know what role the Qlogic 5602 Fibre Channel switch plays with respect to initiators and targets or if it has any role at all. Is it just a "pass through" and the ports on the 5602 do not have to be included? Maybe I don't have the SAN volume available in read/write. I find bits and pieces in blogs and forums, but nothing that puts it all together. I also find that many of the notes on the web are not accurate.
This all may appear simplistic to someone who works with it a lot and if you know of an obvious reference I should be using, a link or reply would be greatly appreciated as I continue to Google for information.

Thanks for the reply. I had previously read the CAM 6.5 manual and have all the SAN configuration and mappings. Yesterday I was back at the site and was able to place a UFS filesystem on the exposed SAN LUN which was 0. I've not seen any reference to LUN 0 being a placeholder for the 2540 setup and when I assigned it, I allowed the CAM 6.5 software to choose "Next Available" LUN and it chose 0. LUN 31 on the 2540 is the "Access" LUN that is assigned automatically - perhaps it is taking the place of what you describe as the LUN 0 placeholder.
I was able to put a new UFS filesystem on LUN 0 (newfs), mount it, and copy data to it. The disk naming convention that Solaris shows for the SAN disks is pretty wild and I usually have to reference a Solaris book on the standard scsi disk name formats. My question/confusion at the moment is that I have 3 Sun branded Qlogic HBA's in the Sun T5220 server - QLE2462 (dual port) with one port on two of the HBAs cabled to the Qlogic 5602 FC switch which is cabled to the A and B controller of the SAN 2540 - there are only 2 cables coming out of the 5220; the 3rd HBA (for future use) has no cables to it. Both ports show up as active and connected on the server down to the SAN and the CAM 6.5 software automatically identified both initiators (ports) on the Sun 5220 when I mapped them. I had previously mapped them to the Sun host, mapped the host to a host_group, virtual disks to volumes, volumes to....etc.; and was able to put data on the exposed volume named dev_vol1 which is a RAID5 virtual disk on the SAN.
When I use the format command on Solaris, it shows two disks and I assumed this represented the two ports from the same host 5220. I was able to put a label on one of these disks (dev_vol1), format it, and put data on it as noted above. When I select the other disk in the format menu, it is not formatted, won't allow me to put a label on it (I/O error) and I can go no further from there. The CAM 6.5 docs stop after they get you through the mapping and getting a LUN exposed. I continue on the in a Solaris-centric mindset and try to do the normal label, format, newfs, mount routine and it works for the one "disk" that format finds but not for the other. The information from the format info on both the disks shows them as 1.09 TB and that is the only volume mapped right now from the SAN so I know it is the same SAN volume. It does not make sense that I would label it and format it again anyway, but is this what I am supposed to see - two disks (because of 2 ports?) and the ability to access it through one. I found out by trial an error that I could label, format, and access the one. I did not do it from knowledge or looking at the information presented....I just guessed through it.
I have not "bound" the 2 or HBAs in any way and that is on my list as next because I want to do multipathing and failover - just starting to read that so I may be using the wrong language. But I am wondering before I go on to that, if I am leaving something undone in the configuration that is going to hamper my success in the multipathing - since I cannot do anything with the 2nd "disk" that has been exposed to Solaris from the SAN. I thought, after I labeled, formatted and put a filesystem on the one "disk" I can write to that the other "disk" that shows up would just be another path to the same data via a 2nd initiator. Just writing that does not sound right, but I am trying to convey my thoughts as to what I logically expected to see. Maybe the question should be why am I seeing that 2nd "disk" in a Solaris format listing at all? I have not rebooted any time during this process also and can easily do that and will today.

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.
- Young

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.

Live Migration : virtual Fibre Channel vSAN

Virtual Fibre Channel had sense in pre-R2 times when there was no shared VHDX and you had to somehow provide fault tolerant shared storage to guest VM cluster (spawning iSCSI target on top of FC was slow and ugly). Now there\s no point in putting one into
production so if you have issues just use shared VHDX. See:
Deploy a Guest Cluster Using a Shared Virtual Hard Disk
http://technet.microsoft.com/en-us/library/dn265980.aspx
Shared VHDX
http://blogs.technet.com/b/storageserver/archive/2013/11/25/shared-vhdx-files-my-favorite-new-feature-in-windows-server-2012-r2.aspx
Shared VHDX is much more flexible and has better performance.
Good luck!

Plugin for EMC VMAX fibre channel storage

I am new to Oracle VM and VM Manager. After reading the documentation, I believe that I need a plugin for VM Manager to discover our EMC VMAX Fibre Channel SAN LUNs. As it is now, discovery on its own does not show the LUNs. Where can I get this plugin? I contacted EMC and they know nothing about a plugin.

It will use the Unmanaged FC Storage Array functionality. If you are not seeing your VMAX luns, check that multipathd is started on your Oracle VM Server and that multipath.conf has the correct device {} stanza for the VMAX.

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.

April fools! I wish I saw this earlier, I would have posted corroborating test results!
In Summary: forget Jumbo Frames for FC !

Fibre Channel Storage

Im planning on using three mac pros to capture live footage in prores 422hq 1080i.
Can I put a fibre channel in each mac pro and network them to each other...that way when i edit i can just edit from each drive from one mac pro without having to copy them all to one station?

What you're asking is called arbitrated loop.
You can start from here:
http://en.wikipedia.org/wiki/Arbitrated_loop
My preliminary kinda lame and super-fast answer is that you'll be involved in a messy configuration, which isn't gonna worth the cost and time.
If you're gonna use fibre channel, buy a switch a proper SAN and do that. Otherwise it is possible to use Gigabit Ethernet switches, a mac pro as a host and work with ProRes.
If you're gonna use the MacBook pro, absolutely check if the GigE port supports jumbo frames because most new iMacs do not.
