5508-HA standby in Maintenance mode
My standby controller is in maintenance mode. Other post say to simply reboot the standby but I'm worried about doing this during business hours. Say I did reboot it during business hours, would it affect the active controller? All redundancy links are connected.

No it won't affect the active controller:
While booting, the WLCs will negotiate the HA role as per the configuration done. Once the role is determined, the configuration is synced from the Active WLC to the Standby WLC via the Redundant Port. Initially WLC is configured, as Secondary will report XML mismatch and will download the configuration from Active and reboot again. During the next reboot after role determination, it will validate the configuration again, report no XML mismatch, and process further in order to establish itself as the Standby WLC

HELP: WLC AP-SSO not working (standby unity in maintenance mode)
I have two WLC version 7.3.101.0 with the standby unit having HA-SKU. I have tested the AP-SSO functionality without any problem in lab with direct connection on RP port between two WLC. Once I brought them into data centre in separate location (latency is less than 10ms between the two DC), the standby unity always went into maintenance mode. The booting process on standby unit went to maintenance mode as shown below:
Management Gateway and Peer Redundancy Management interface are not reachable.
Entering maintenance mode...
I have checked on the core switches at 2 data centre that the two WLC RP ports are connected to same VLAN and it is spanned across MAN link (10GB and less than 10ms delay). The spanning tree on those ports are forwarding as well.
I have rebooted the second unit but no luck.
The interface between two DC is using MTU 9216 which I do not think would cause this issue.
Anyone has come across same or similar issue with me or know the solution? If you do, plz enlighten me.
ThanksThanks Leo and Scott for your feedback. I notice there are two newer software for WLC version 7.3.102.0 and 7.4.100.0.
Both of them seem to have many open caveats. In my wireless environment, I also use ISE, MSE and Prime Infrastructure and unfortunately WLC 7.4 does not support prime solution and MSE yet according to below compatibility matrix.
http://www.cisco.com/en/US/docs/wireless/controller/5500/tech_notes/Wireless_Software_Compatibility_Matrix.html
I think I only have choice to do minor upgrade to 7.3.102.0 at this moment (please correct me if I am wrong). This software was published on 30th Jan 2013 so I wonder if someone else has tried this and managed to get WLC AP-SSO setup working flawlessly where 2nd WLC unit is at different location?
Appreciate for more info and advise. -
We have 2 wlc 5508 with software 7.5.102.0, both wlc have 25 AP license.
We try to setup HA SSO but 1 wlc in maintenance mode: Maintenance cause= Incompatible Software license
Could you help me ?
thanks.

http://www.cisco.com/en/US/products/ps10315/products_tech_note09186a0080bd3504.shtml
If you want to convert any existing WLC as a Standby WLC, do so using the config redundancy unit secondary command in the CLI. This CLI command will only work if the WLC which is intended to work as Standby has some number of permanent license count. This condition is only valid for the 5500 WLC, where a minimum of 50 AP Permanent licenses are needed to be converted to Standby. There is no restriction for other WLCs such as the WiSM2, 7500, and 8500.

Logical standby in noarchive mode
Hello,
does anybody know if it is possible to run a logical standby (10gR2) in noarchivelog mode?
For my understanding it should be possible, why not... But I can't find a piece of documentation which prove this.
Thanks in advance,
Boris...I also was curious if setting up a Logical Standby in noarchivelog mode was possible. It looks like it is...
We use this simply as a reporting copy of our data. Our analysts do not change any of this data. They just need it to be fairly current (~3 days). At this point, there isn't any need to generate archivelogs so we want to disable the feature to minimize our maintenance and our storage requirements.

My 3050 J610 printer goes into standby or sleep mode and then I cannot print docs to it wirelessly
Everytime I do not print something for a few hours, my printer goes into standby or sleep mode. When it does this, it cannot be used to print from my laptop or android to it. Is there a way to set this up so that it doesn't "go to sleep" and it is always available to me to print with. I like the printer, but it seems kind of off that you cannot print on it wirelessly and it is considered a WIRELESS printer. That's the only reason I bought it and now I can't even use it without walking downstairs and turning the printer back on again. If I wanted to do that every time I would just print from my main computer!
Thanks,
Ashley
This question was solved.
View Solution.Ok, I know this thread is a little old, but it would not allow me to start a new one, since I am new. I am having the same issues with my 3050 J610 as everyone else. It makes you think there is a wireless connection problem, but that is not the case. The printer goes into a standby mode and there is no way to bring it out of it, unless you cycle the printer. The panel buttons will still work, you just lose the ability to print wirelessly.
I have had my 3050 J610 in two different rooms, master bedroom and basement office. Both areas work well when it is connected and awake. After a while of inactivity, it goes into standby mode and cannot print wirelessly. Here are steps I have taken so far:
When the printer goes into standby and will not print wirelessly, I have check to make sure there is still a connection between the router and the printer - There is
I have set a static Id for the printer at .210
Cycling the printer brings the connection back instantly.
The front panel buttons work just fine when it does not have connectivity
In the basement, the machine has excellent signal and connection.
I have checked the recommendations in this thread, and like others, there are no options under the advanced tab of the maintenance page. The problem is a standby or sleep issue. When this arises, it has connection to the router, but the wireless computer does not have connection to the machine. I know when it was in the bedroom, the light would blink 3 or 4 times now and then throughout the night. We need a way to turn off the standby, or bring the machine out of standby mode. It is not an issue of the router, channel, interference, or software. It is the sole issue of standby or sleep modes. I have been pulling my hair out for almost two years over this issue. I swore I would not buy another HP product after the problems I had with a printer and laptop. But I thought I would give HP another chance. -

Warning: The system has not been taken off maintenance mode completely
After I enabled Maintenance mode using adadmin, I ran Compile Flexfields. Then I disabled Maintenance mode. But, on the 11i login page, I keep getting a warning message:
Warning
The system has not been taken off maintenance mode completely. Please contact your System Administrator.
I am sure I disabled the Maintenance mode in adadmin. Why I still get the warning? How to fix it? Thanks a lot.Thanks a lot. That is the fix.
One more question. After I ran "Compile Flexfields", I got
Number of successful descriptive flex compilations : 7520
Number of failed descriptive flex compilations : 1
How can I find the failed description flex? The log does not give info on this. And, how to fix it?
Thanks a lot for your help. -
Cairo-dock starts in "maintenance mode"
Hi,
I've recently upgraded the cairo-dock, but since then it starts along with the <maintenance mode window>... When I try to close it, it reappears until the wifi connection settles down. I suspect that weather-dock is making troubles when it does not have connection to the internet.
I've looked through the cairo-dock options, and it has an option to force maintenance mode, but it does not have one to force disabling it unfortunately.
Anyone has any idea how to get rid of this?probably an issue with your configuration. had this once, deleted my .config/cairo-doc ( at least i think thats where it was) folder and it worked again - with default settings.

OM2012 – Putting a Monitor in maintenance mode
Hi there,
I need to write a powershell script to put a Monitor in Maintenance mode. This is easily doable manually on the console whenever an alert comes up by putting the alert in Maintenance Mode.
So far I managed to make my script to put the class of the Monitor into maintenance, as per bellow
i.e. if the monitor is “Total CPU Utilization Percentage”, it would put Microsoft Windows Server 2012 R2 Datacenter in maintenance mode for the computer $ComputerName.
$ComputerName = Read-Host “Enter computer name”
$MonitorName = “Total CPU Utilization Percentage”
$Monitors=Get-SCOMMonitor -ComputerName $strComputerName | where {$_.DisplayName -eq $MonitorName}
$Time = ((Get-Date).AddMinutes(6))
foreach ($Monitor in $Monitors) {
$Instance = Get-SCOMclass -name $Monitor.target.identifier.path | Get-SCOMClassInstance #| where {$_.Path -eq $ComputerName}
Start-SCOMMaintenanceMode -Instance $Instance -EndTime $Time -Comment: “Server maintenance”
I can’t figure our how to simply put “Total CPU Utilization Percentage” (or any other Monitor) in maintenance mode
Thanks for your help !Yes, use the "Start Maintenance Mode" Activtiy of the Integration Pack for OpsMgr.

Hi,
We planning to go one level higher to automat and have more dynamic Software Update Management for Windows Servers. We have SCCM 2012 R2, SCOM 2012 R2 and SCO 2012 R2.
Our plan is to pur server in an AD-Group to get Update Schedule, from the servers will be importet to an Collection for Automatic Update and reboot. If I understand Everything right SCOM can't read AD-Group and put then in an Schedule maintenance mode. SCOM
can read reg value as exempel.
IS there any smar way to make the SCOM Maintenance Mode Schedule dynamic?
I found this
http://www.scom2k7.com/scom-2012-maintenance-mode-scheduler/?
/SaiTechYou could use Orchestrator to put the servers from a specific collection, or AD group, in maintenance mode in SCOM. For an example see:

Unable to enter maintenance mode - dtrt1000
Over the last few weeks my box is almost useless. With frequency it only part records, freezes requiring rebooting, momintary screen blanks, and is generally a pain in the rear. I've tried to get into maintenance mode to try and reset it, but following the guide from Youview it doesn't work, and the box just starts as normal.
My understanding is that you (1) Switch the box off from the back (2) Switch it back on after 30secs (3) Press the power button and immediately hold of the -vol button until the splash screen appears...Then you can access the menu.
I've tried holding the holiding the -vol button before the power button, holding it immediately after power button, holding it until the nearly ready screen, in low and high eco modes etc but get the same result, it just goes straight into normal programes???1 Start with the YouView box powered off from the switch on the REAR panel power button
2. Power back on the YouView box using the REAR panel power button
3. When the FRONT power button is illuminated with an orange circle, press the FRONT panel power button firmly once and it will turn blue
4. Immediately press and hold the "VOL-" button which can be found on the right of the FRONT panel the first silver button.
5. A message saying "Enter Maintenance Mode Y/N (Y: POWER)" appears on the TV screen
So if I understand correctly your experience is that steps 1, 2 & 3 occur but when doing step 4 the message step 5 (does not occur ) and your box boots as normal.
My own (historic ) experience is that the timing of stages 3 and 4 is quite tight - ie the power button turning blue followed immediately by the VOL- button being pressed and held.
Your options if the maintenence mode will not work are to contact BT support and seek their advice or if you are not concerned about the recordings remaining on the box you can do a factory reset from from main Youview menu

All services stuck in maintenance mode
I've got a problem on Solaris 10. All of the enabled inet services are in maintenance mode. rlogin, ftp, telnet, stlisten, xfs, etc, etc - are all in maintenance mode. The inetadm command shows no online services, only disabled and maintenance. I've tried clearing them with svcadm but they won't clear. It won't show any explanation for why.
What could be wrong to cause this?
Thanks for any suggestions.
RandyThanks very much for the very helpful suggestions. svcs -xv does not show anything helpful - for the Reason, simply "Restarter gave no explanation". The svc:/network/inetd:default is indeed enabled and healthy.
/var/adm/messages, however, has information that might point to the problem. Regrettably, I don't understand the message and am hoping someone here can enlighten me. For each of the services that is in maintenance mode, these messages appear:
Nov 3 17:59:44 trsun006 inetd[322]: [ID 702911 daemon.error] Property exec for method inetd_start of instance svc:/network/login:rlogin is invalid

I don't understand what it means by "Property exec for method inetd_start ... is invalid".
I issued these commands-
[trsun006 27] sbin > inetadm -l rlogin | grep exec

Need to place the SCOM agents in Maintenance Mode automatically during Patching activity
Hi,
I have a requirement to place the SCOM agent servers in MM automatically during shceduled patching every month. I have gone through few blogs but could not find an apt solution for SCOM 2012 R2 environment.
I think the process should be..
1. Create a management pack to monitor all servers for event 1074 (or/and 22), which gets triggere during the patching
2. Write some powershell to put a machine into maintenance mode.
3. Trigger the powershell script to run when needed.
Any suggestions please?
ThanksWhere doing this in our environment. We have a SCOM monitor looking for Reboot events (ID 1074) where the event contains Shutdown Type: Reboot. the monitor creates an Informational alert which Orchestrator picks up and then sets the machine in MM for 30
minutes. So its any time the machine is intentionally rebooted. You can have it look for CcmExec in the Event description (assuming you're using SCCM) if you only want it to work when being patched.
