• UCS kvm - connection failed

  Hello

  I encountered problem with kvm.

  When I try to run the kvm console, I get "connection failed", but I managed to connect only once in 10 times.

  I have "Management Pool of IP" and I can see the ip address assigned to my blade server.

  Is that someone has the same problem?

  Thank you!

  To fix this problem with CICM (KVM) access, make sure that the Pool(ext-mgmt) IP management is part of the same VLAN as the FIC IP subnet. CICM access is provided on the MGMT 0 and interface 1 on the FIC and not 10GB uplinks.

• UCS KVM issues, must remove a pool and let the pool questions

  We currently have multiple pools in our model and recently a new blade from the last pool that has been added, and we cannot have it use as it is in a different subnet from the FI.  KVM will not work in this case.

  Thus, management fired one IP address of this pool, and the KVM does not connect because it is on a different subnet as the FI.  We want to remove this pool, so this does not happen and reset this blade is on the other subnet 10.1.0.xxx which will allow the KVM start work. And we do not want to provoke the interruption of all the machines that run on this blade, since it's production.

  My question is really, if we remove that pool, the blade will automatically happen to other existing pools?

  What happens to the other KVM on the slides that currently use the pool for a KVM to this POOL session we want to remove?

  As seen in the screenshot, we have blade, 1 and 2 have a kvm fired him.  Blade 3 and UCS8 is the new blade and must be handed over to another pool.  What happens if this pool is deleted in this scenario?

  See screenshot.

  If you remove the ext-mgt-pool (for external access of MMIC), the IP address are removed immediately from the MMIC. No restart of the server, nor MMIC. You can set a new position-mgt-pool, and an IP address is automatically assigned to each blade.

• Change the IP for UCS management pool

  Hi all

  We try to change / less the size of the property held by the pool for blades UCS KVM management.

  Some IP addresses are assigned to the existing blades, pourrais I delete existing IP pools directly and create the new compact block for managing KVM?

  If I like the above, I know I'll lose KVM on the blades.

  In addition, what is the impact? The trafffic server will be interrupted or blades restart?

  Thank you very much!

  Best regards

  No harmful impact other than to lose access MMIC for awhile (kvm, virtual media, IPMI etc.).  Blade will not restart you.  It's strictly a connection out-of-band management.

  Create your new pool, then zap your old.  The blades will be immediately wish through the other pool for an available IP address.

  Kind regards

• Error UCS Manager Console KVM to open after Java Update

  After the upgrade to version 1.7_21 Java I tried to access the KVM console from within the UCS Manager (v2.1 (1 d)) and get the error message:

  "Cannot run the program"C:\\Program": CreateProcess = 2 error, the system cannot find the file specified."

  I tried to remove installed applications and applets as well as temporary files from the Java console inside, but it does not solve the problem. We also tried to launch the console KVM in KVM Manager and that works very well. Everything works correctly when you run Java 1.7_17.

  Everyone knows about this problem since upgrade to 1.7_21?

  Thank you.

  In the meantime, you can install Java in a directory path that has no space to work around the problem. For example: c:\Java\jre7

  This will give you access KVM again.

• Keyboard cannot work after launch KVM in UCS

  I am facing a strange problem to install ESXi to a UCS B200 M2 blade, after replacing the two hard drives, I try to install ESXi on this blade again, but after the launch, the KVM, seems my keyboard cannot communicate with KVM, means I will not push "enter" to start the installation. All the key stop working, even use "macros".  This problem is only happening on a blade, no problem to use KVM for communication with the blades of rest. Already tried:

  a. retrieve this blade.

  b. re associate this blade with the service profile

  c. re install java on my laptop.

  d. try on a different workstation

  But still does not work. all the blades with the same profile adjustment services actaully.

  Enjoy can get advice from here. Thank you very much!

  Yang,

  Can you make sure that the MMIC is running the same version as the UCSM and check the results.

  Also, you can try a MMIC and a CMOS reset to see if that makes a difference.

  Thank you!

• To access the DNS - MMIC - UCS direct KVM ip address name

  Hello community,

  I have a little problem. We use 2.2 (3d) UCS and 32 M3 B200. Now, I want to use a direct KVM access.

  For all 32 blade servers, we have created the DNS for their IP MMIC entries addresses.

  example: ESXserver1.rc (servername + ".rc") 192.168.0.1 <-- --="">(address IP of MMIC)

  If I enter the IP address of MMIC in the browser, direct access KVM works very well.

  If I get the DNS name in the browser, direct access KVM page load, I connect and get the following error message:

  GetKVMLaunchUrl: Invalid or IP address of zero MMIC spent

  Can someone help me? What do I have to configure something?

  Concerning

  Hugo

  Hi Danny Sander,

  By DNS name it won't work even if you have created in the DNS entries also, because it works through the address IP of MMIC mangement.

• Use management/KVM ip addresses several areas of the UCS

  Hello

  We organize several servers UCS blades in two areas of the UCS. In all areas, we configured an IP ext-mgmt pool to join the MMIC of the blades. As our two infrastructure is developing, I was wondering if we could use the IP addresses that we use for pools in both areas?

  I read the guide management (http://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/ucs-manager/G...) and as far as I understand it, if we use the inband IPv4 addresses these addresses are used between the fabric interconnects and server blades?

  So I could not addressed the KVM from "outside" so through the UCS Manager (equipment-> frame-> Server-> Actions "Console KVM"). Am I wrong? I did a few tests well failed to start KVM without our current configuration (IP ext-mgmt pool provides extrabande for each unique server IPv4 addresses).

  Thanks in advance!

  Concerning

  Martin

  Hi Martin

  I think that's not possible! as soon as you insert a blade, it will have an IP address from the ext-mgmt pool and assigns it to the MMIC! That's why this IP address is assigned to a chassis / slot, which means that if you move the blade to another location, most likely, it will get another address. It is a challenge, if you want a DNS entry for a blade / KVM access.

• Revoked certificate of UCS Express E140D MMIC KVM

  So I have a bunch of 2951 s with E140D blades in them. I need to install ESXi on them but the stinking KVM (accessed via the MMIC) for each of them comes with a revoked certificate error.

  I just did this for a bunch of M3s C240 with no problems.

  CIMC firmware version is:

  2.1 (1.20130726203500)

  This appears to be later - I just downloaded the latest version and the number corresponds to the existing version.

  I did not open a TAC case again; I have problems with phone and my serial number don't like the online form. However, I'm going to miss a deadline for this reason.

  Here's the traceback of java:

  Hi Michael,

  It seems that you hit a bug for the E series: CSCtx85249.

  You will follow it please workaround for

  CSCtx85249    Could not launch KVM Java exception that certification was

  revoked

  Console KVM symptom does not start and displays the following Java

  exception error:

  Certificate has been revoked

  sun.security.validator.ValidatorException: PKIX path validation failed:

  java.security.cert.CertPathValidatorException: certificate has been revoked

  Solution to workaround on the client system, disable the configuration of Java

  the Java Control Panel settings follow these steps:

  Step 1 go to advanced > Security > General

  Step 2 using CRL revocation checking certificates

  Enable line stage 3 validation of certificate

  If you use Mac, in addition to modifying the Java preferences, you must

  to change the CRL and OCSP checking off

  underKeychain > preferences > certificates under OSX.

  In some scenarios, you must do the following if you are a Mac user:

  Step 1 go to keychain > certificates. Double-click on the cisco.com partner

  certificate.

  Step 2: click the right arrow for Trust and select always trust in the when

  using this certificate dialog box.

  Step 3 restart the browser and connect to the MMIC web

  interface.

  Please, let me know if that solves the problem.

  Thank you

• Good role/privileges to access KVM only in UCS

  Hello

  I do a few locally authenticated users for some people to work.

  They wish to access KVM and do things there.

  What role/privileges do I need set the user?

  Hello

  Try to associate the user with a role that has privilege only 'service-profile-ext-access' in it.

  According to me, which will only allow the KVM access on the blades.

• UCS C220M3 KVM

  I have a MMIC 1.5.1b version. I can launch the KVM on place where the servers are. If I try to launch KVM thru aa VPN connection, that it will not start.

  Same issue on Firefox, IE and Chrome.  Java is current, and even in the Java log I don't see anyhing...

  If I use the same pc and vpn in my LABORATORY, all right.  I've heard of people seeing this issue, but nobody has posted no response...

  Thank you

  Mike,

  KVM uses the port 2068 to communicate on the network, make sure that the port is allowed via VPN and its is not blocked by firewalls or ACLs. You can try to telnet to the server address MMIC using port 2068 to test connectivity on this port.

  Also, are able to launch KVM from any other version of CIMC on the VPN connection directly you form your PC?

• UCS C460 M2 - error 1902 during the firmware upgrade

  Hello!

  A few days ago, I could upgrade the firmware 1.5 (7 c) to 1.5(8a) and the BIOS to version 1.5.4a to 1.5.4b using file ucs-c460-huu - 1.5.8 has mapped via KVM using an old windows xp with java 1.7. In fact, this upgrade would allow access of latest java KVM, something that was lost a few months ago.

  On Monday, I did the same procedure on an exact server and everything was fine, but this server cannot update firmware.

  I get error 1902, described here:

  https://Quickview.cloudapps.Cisco.com/QuickView/bug/CSCui18044

  But there is not something to solve this problem.

  Any ideas please?

  Concerning

  David

  David,

  A few steps to try:

  -Turn off the server, remove the power supply and press and hold power for 30 seconds. Retry the upgrade.

  -Restart the MMIC before the upgrade.

  -Try the upgrade using a physical USB vs vMedia

  Let me know what questions you have and please share the results.

  Thank you

• Role of the KVM

  Is it possible to create a KVM in UCS Manager role?

  We use LDAP for authentication and we want to map a group to a role that would only allow KVM access.

  The users in the role of the KVM would be able to see a remote console, the server power to power, attach the brackets (ISO).  But we don't want them to be able to change the settings of the service profile like the addition of the NETWORK card or a policy change.

  Is this possible?  I don't see a built-in KVM role.

  You can create a role called kvm access or what you want to name and then give him the privilege of "service-profile-ext-access." You can then map the role to an ad group.
