Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.

I help out a charity that has a Windows server 2012 R2 running as Essentials. Exchange is done by office 365.  Twice now, they are loosing access to the server and internet (as the DNS server for the machines on the LAN) after a few days.  A reboot cures everything.  I have an RMM agent on the server and both times, the server last checks into the RMM tool around 4AM.

Wondering how to troubleshoot that.

Some background:

Recently, there was a lightning strike nearby. Fried the key card door entry system, alarm system, phone system along with some of the computer network

Side note / question: the other systems were OLD... electronics are more susceptible to surges as they age, right?  caps dry out, etc.  A surge that might have not affected a newer machine could cause more harm to an older system?

Anyway, it blew out the main 16 port switch in the telco closet.  Getting that replaced.  Blew out a couple older data switches in a couple offices (using a single data line to that office to put the printer and PC on the internet), blew out a PC and monitor in another office.

The server appeared to be OK... but we're starting to see that need to reboot it.  twice now, they lose access to the server from the machines on the LAN.

Sitting at the server, I can ping it's own IP address.  Can't ping any other IP addresses.  From other machines, can ping other machines and the router.  I can do most anything - browse files on the server, check event logs, open apps. …

I have a HP ProLiant 360p.  The eject button on one of the drives is lit red.  Does this mean it has failed?

Are the power supply to SATA hard drive power cables the same for both the Corsair AX1200i and Thermaltake TGB1200W power supplies?

Is it safe to interchange these power supply cables between the two power supplies?

I recently had a server that we were trying to update the drivers and firmware.  After I downloaded the SUU from Dell and burned to a DVD, This updated a few things bit a;sp saw error""Can't open IPMI device".

I have tried:

1)  Pull power, hold power button 1 minute.  Release, reapply power cords and start.
2)  Hold blue button 15 seconds to soft reset

After SUU finished we still see the error.  I simply cannot believe that the whole server is not bricked because the Lifecycle Controller failed to update iDRAC/IPMI firmwares.  This seems nuts and a huge flaw that will have me never updating another Dell server firmware ever again.  

Another thing to note is that this server had an iDRAC enterprise license.  I have read that the solution here is to replace the motherboard and I can get a refurbisghed motherboard  fairly cheap but I am sure I will lose my iDRAC enterprise license in that process because the license is tied to the machine (and I am not even sure I have the file any more).

I feel there has to be some other option other than replacing the entire motherboard, as I see a ton of refurbished boards out on the internet.  I feel someone else has ran into this problem other than me.

Anyone knows Aruba controllers well?   They normally pass through the same VLAN on the main switch, or the management VLAN.
Wonder why Aruba not recommending doing a direct heartbeat between Active and Passive controllers.  Using 7030 controllers at this point.
Normally I do a direct heartbeat between Cisco controllers.  But Cisco has a dedicated HA port for this.  Arubas not.  7030 controllers have 8 fiber and 8 copper ports.
 Anyone knows about it and have an advice?

Dell PowerVault MD1200 with 8 drives in RAID 5, (2 TB each) (2, 4 drive arrays).
There were 3 arrays but two drives simultaneously crashed so I pulled all 4 out. About 2 weeks later the whole system died. When you unplug it (and reboot the server too) and replug it in, it starts to boot, recognizes all the drives the the fans in both power supplies go FULL blast and REALLY loud.
The virtual drives are recognized by the OS for about 10 or 20 minutes until the system dies again.
Only thing I can find is on the back the EMM light is blinking amber twice at a time but I'm not sure thats it.
I've tried booting up with either one or the other PS plugged in, same result.

Thanks!

Does anyone know the trick to getting an IBM 81Y7007 Redundant Cooling Kit (3x fans) to be recognised in a X3500 M4 IMM2? They have been installed in positions 4, 5 and 6 (redundant positions) however do not show in the IMM2 even after rebooting the IMM2. Fans are running.

IMM2 GUI and CLI only show the 2x factory fans:

system> fans
Fan 1 Tach 40%
Fan 3 Tach 40%

Open in new window

Do dual processor work as redundancy?  If one fails will the server or PC still boot up?  Or Dual CPU only speeds up the process ?

10gbe network server 2012 essentials windows 2016 essentials.

Have just installed a new 10gbe switch all with Cat6a cable which currently runs into a netgear XS728T

In server 1 running 2012 is a x550t
in server 2 running 2016 is a x722

I have noticed that I have installed on server 1 the new proset drivers which gives me full access to teaming etc, as seen in attached.

Now I've put on jpref and achieve full 100% network usage on the 10gbe cards.

When I go to use windows i Get 150-250mb have checked if it was the disk by using a ram disk and all the raids will easily outperform this. I'm testing a file which is 7gb and not lots of little files.

Thanks

Hello Experts,

We have a Dell MD3260 storage array. on one of the two raid modules has a error battery status "Not Available".  The battery has been replaced multiple times and this error still remains.  No amber lights are lit on the raid controller.  Could it be the raid module its self that is the issue?    

Thank you,

GTS

Hello,
I have few offices that I need to support, I always assist remotely the business users.
Was wondering if there is a KVM switch that connects to the internet, and then I can plug it to a computer via USB and VGA so I can control the machine remotely, even via the bios. Kinda like HO iLO.

Any recommendations ?

This course will introduce you to SQL Server Core 2016, as well as teach you about SSMS, data tools, installation, server configuration, using Management Studio, and writing and executing queries.

We have an HP Proliant server, it will suddenly switch to "high performance" that the fan is very noisy. It happened around 2 times a day, and last for 10 - 20 seconds

Called HP technician checking the hardware, and nothing found. Having look at the event log, but no idea.

There is no system change recently, and more interesting it happened even there is no end user in office (but only me) .... Any idea?

Hello:

I am running a Lenovo Think Server TS440, running Windows Server 2012 R2.  About a month ago the server was having connectivity issues, with packet loss between the NIC and the Router.   I changed the cable, replaced the SonicWall router, and installed a new NIC.

After replacing the NIC on the Server everything worked fine, now I am having the same issue again.  All the other PC's and servers do not have any connectivity issues to the router.

I find it odd that a New NIC card would fail after a month with the same symptoms.  Any advice or suggestions are greatly appreciated.

Dear Expert Friends,

I have a ProLiant ML350 G6 server that was put into services on 5/24/2011. Natually the warranty is out and my customer is dragging their feet on purchasing a new server. At any rate the server is rebooting nearly every morning at the same time and throwing POST errors. After some research I found that the HDDs need their firmware updated. I've lived my entire tech carrer in the Dell world and on top of that I've never had to update firmware on HDDs that are in a RAID configurations. Would someone out there be so kind as to provide me with the proceedure to update the firmware on the HDDs with out destroying the RAID configuration or loosing any data. This server belongs to a medical clinic and is very crucial to their practice. I have very little opportunity for down time so I have to have my game plan down cold. Can someone help with the steps and any management software that might help with this task? I've searched and searched but cannot find anythng that provides me step by step instructions and provides me with reassurance that I will not loose data. See below for specs. Also is there any order in which I should do updates. For example, update BIOS, RAID firmware, then HDD firmware? Have you ever seen anyone loose data doing any of these tasks?

Reason for needing upgrade is the HP Proliant Integrated Management Log Viewer is giving POST error: 1770-Slot X Drive Array -Disk Drive Firmware Update Recommended. When researched I found this

I have 2 disks in my Proliant DL380 which are mirroring each other.  I need to add another disk for storage.  I do not want it part of the RAID just a disk for storage.  I installed the disk but the Server running Windows Server 2016 Data Center does not recognize it.

Thanks for the help please!
