This is just a quickie. When you want to reset Splunk Index into default empty state, you can run following commands:
root@splunk01:/opt/splunk/bin# ./splunk stop
root@splunk01:/opt/splunk/bin# ./splunk clean eventdata
root@splunk01:/opt/splunk/bin# ./splunk start

Once a while web-based update for firmware on IBM FlashSystem doesn’t work. Or it takes long time to finish. Then there is a time to make update manually by following steps:
cleardumps -prefix /home/admin/upgrade
pscp.exe [FILE_TO_UPLOAD] superuser@[IP_FLASHSYSTEM]:/home/admin/upgrade
This bug with problem to upload huge files into FlashSystems are since 8.6.x.x of firmware.

This is very fast quickie. When you want to find which directories take most of the data on Linux use following command:
du -h -x -d 2 / | grep G
You can change “/” to corresponding directory you are interested in.
Have a nice day,

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:
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:
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:
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,
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.
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:
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…):
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:
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,
Trvalo mi nejaky ten cas kym som pochopil (vsimol si v zatvorke), ze “Nastroj na pripravu systemu” je po nasom SysPrep 🙂
Naco to prekladaju? Len s tym matu nepriatela. 🙂
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’.
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
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
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.
I was browsing at Brocade website lot last couple days, but when I accessed it from my Internet Explorer 10 I received following warning:
I thin Internet Explorer is out for a quite time, so Broacade had time to “implement” it on its website 🙂
