Lenovo/IBM manual update from BOMC medium

September 23rd, 2015 2 comments

Couple days ago I had following problem. I wanted to install the newest firmwares on Lenovo (IBM) x3650 M5 server. I used Bootable Media Creator to create CD with latest firmwares for this machine. Problem came when I looked into firmwares BOMC wanted to upgrade:

BOMC

BOMC

Problem was that I wanted to upgrade firmware for SAS card ServeRAID N2225 which was installed in this server. This card is also supported and there was also new firmware downloaded into BOMC directory:

BOMC

It looked like BOMC didn’t detect card in server and therefore it didn’t put it into the list of firmwares which should be upgraded. I tried other server which was in same configuration and it was same result. Then I tried to press ALT+F1 combination in BOMC. New bash shell came on screen. I tried list directory “ls -al” and I was there are all the files with firmwares. So I have tried to run binary with mentioned firmware:

BOMC

Tadaaaaa….firmware upgraded. It looks like Lenovo has some bugs in its tool BOMC. I hope Lenovo support will get at least close to IBM support.

Have a nice day,

HP wasn’t ready to split

August 4th, 2015 No comments

Yesterday I was trying to download HP Service Pack for ProLiant (SPP) from HP.COM website. It didn’t work at all – still some HTTP errors. Finally I found out that HP moved all its stuff to new domain hpe.com (HP Enterprise). That’s fine, but they forgot to rewrite all urls on websites to new hpe.com. 🙂 Finally I tried couple google hacks and I found HP FTP server where I could browse and find what I was looking for ftp://ftp.hp.com/pub/softlib2/software1/cd-generic/p67859018/.

Maybe this help someone faster than looking on slow HP’s websites.

Problem with opening files on RDS Farm

June 28th, 2013 No comments

I built RDS farm (Windows 2008 R2) at one of our customer. Customer has his own website where he has links to Excel files on some share. When some user tries to open file from this website he gets following question:

Open files

This is normal behaviour. So let’s press Open and we get following error (The file you are downloading cannot be opened by the default program. It is either corrupted or it has an incorrect file type…):

Problem screen

This says that default program is corrupted or it has incorrect file type. Huh? Excel is working fine and also it’s opening files 🙂 So you can Save file and then open it. Then it works fine.

So I started to google and I found one Microsoft KB article, where problem is described. There is also hotfix to download, but there is no hotfix for Windows Server 2008 R2. 🙂 Luckily there is also workaround specified. You can either save file first and then open (which is what we don’t want) or you can tweak registry keys as described in article:

Workaround

When I implemented this registry tweaks everything works like it should. I’m happy they also posted Workaround and not just Hotfixes.

Have a nice day,

Problems with CPU in incompatible error during VMWare vMotion

April 23rd, 2013 13 comments

One of our users reported problems with vMotion after firmware upgrade of IBM server. Firmware were upgraded using BOMC (utility to create ISO images to upgrade IBM server to the lastest versions available).

After upgrade user was not able to do vMotion. They received following error:

Host CPU is incompatible with the virtual machine’s requirements at CPUID level 0x1 register ‘ecx’.

CPU is incompatible

After couple minutes of googling I found out following official articles:

Based on information there is change when you do firmware upgrade. Sometime (from some version) AES feature is Enabled and sometime is disabled. This setting cannot be changed in BIOS and this is really sad. So let’s look at the way you can change it.

In second mentioned article IBM suppose to download some prepared ISO image called BoMC-2.20-uEFI-AesEnable-to-enabled-vmotion-fix.iso. But I couldn’t find this ISO image. So I had to use other way around. I downloaded IBM Advanced Setting Utility. I downloaded and installes version for Windows 64b. You need your RSA card to be accessible through network. Then you can run following command to check actual value:

asu64.exe showvalues UEFI.AesEnable –host RSA_IP_ADDRESS –user RSA_USER –password RSA_PASSWORD

AES showvalue

You can check it on all ESX servers. To decide whether feature should be enabled or disabled you this article. We need to change it to the same setting using following command:

asu64.exe set UEFI.AesEnable Disable –host RSA_IP_ADDRESS –user RSA_USER –password RSA_PASSWORD

set AES

When values are the same on all ESX server you are able to do vMotion. I was kinda mad on IBM, because I would preffer to change this value in BIOS instead of some application.

Fun: Internet Explorer 6 or 10?

April 19th, 2013 No comments

I was browsing at Brocade website lot last couple days, but when I accessed it from my Internet Explorer 10 I received following warning:

 

IE10 or IE 6

 

I thin Internet Explorer is out for a quite time, so Broacade had time to “implement” it on its website 🙂

Very very bad support from Meinberg getting better?

November 23rd, 2012 No comments

Last two weeks I had to update some NTP servers from one German company. When I requested new firmware I received following e-mail:

Dear Sir,
 unfortunately, I cannot provide a new firmware since your compact flash card is too small and the action might end up in a system’s inconsistency.
Thus, you are also not the only customer who is affected by this, we offer bigger compact flash cards for 65€ each. Please let me know whether this is of interest for you and if you need an official offer.
Mit freundlichem Gruß / With kind regards
 

So this made my very upset. To be able to upgrade to the newest version of firmware I had to pay 65EUR for new flashcard. So I wrote couple e-mail to this company. I wanted to know the reason why I need to invest more to NTP server. I found out that firmware got big and it cannot be uploaded into flash which came with NTP server. This looked weird to me. Why would I have to invest into device if manufacter’s engineers made a mistake. I already decided not to sell manufacter’s devices. And I though that was end of the story.

Today I received following e-mail:

Dear Ondrej,
 
I just wanted to let you know that we dramatically improved our update procedure and, after an intensive clean-up, released
the new firmware version 5.34h which can be installed on 64MB compact flash cards without any problems. The new release is 4 MB (~25%) smaller (!) than the previous version without removing any features.
 
Although you already expressed your extreme dissatisfaction with our products and decided for yourself to not recommend or
buy Meinberg products in the future, your feedback helped us to improve our software and I sincerely thank you for that.
 
Best Regards,
 Heiko
 

So it’s funny how some angry and mad e-mails can change such a things. Now we can upgrade our devices. But I don’t think we will offer them anymore to customers 🙂

Great google translation

Today I was at the VMWare ThinApp forum answering questions and I found out nice question asked in very funny and nice way:

 

Is there any Simplified Chinese language pack

Is there any Simplified Chinese language pack

 

I tried to copy and paste it into google translator and it really translated even Simplified Chinese questions 🙂
