Adding a new disk to an LVM with esx

Leave a reply

$ lsblk

Look at disks to check what is already in use

Add disk in vcenter

$ for h in $(ls /sys/class/scsi_host); do

echo ‘- – -‘ > /sys/class/scsi_host/$h/scan
done

$ for h in $(ls /sys/class/scsi_host); do
    echo '- - -' > /sys/class/scsi_host/$h/scan
done

$ lsblk

look at disks, it should be added

fdisk -l

take note of added disk

eg: /dev/sdc

fdisk /dev/sdc
n - new partition
p - primary
1
defaults
w - write

pvscan

take note of disk /dev/sdc1

pvcreate /dev/sdc1

vgdisplay

take note of vg name, eg: ubuntu-vg

vgextend ubuntu-vg /dev/sdc1

pvscan

disk should be added

lvdisplay

take note of LV name (logical volume name), eg: /dev/ubuntu-vg/ubuntu-lv

lvextend -l +100%FREE /dev/ubuntu-vg/ubuntu-lv

resize2fs -p /dev/ubuntu-vg/ubuntu-lv

Reduce RDS SPLA CALS (licensing)

Leave a reply

From https://social.technet.microsoft.com/Forums/ie/en-US/eac06eab-3455-4d8e-8698-ddb8d4189e64/reducing-the-number-of-remote-desktop-licensing-peruser-cals-?forum=winserverTS

We can use the following commands

Get-WmiObject Win32_TSLicenseKeyPack|Select KeyPackId, ProductVersion, TotalLicenses, TypeAndModel|Format-List

Invoke-WmiMethod -Class Win32_TSLicenseKeyPack -Name RemoveLicensesWithIdCount -ArgumentList <Keypack>,<NumberofLicensesToRemove>

For Example, if we had 14 RDS cals, and wanted to reduce them to 12:

PS C:\Windows\system32> Get-WmiObject Win32_TSLicenseKeyPack|Select KeyPackId, ProductVersion, TotalLicenses, TypeAndModel|Format-List

KeyPackId : 2
ProductVersion : Windows 2000 Server
TotalLicenses : 4294967295
TypeAndModel : Built-in TS Per Device CAL

KeyPackId : 3
ProductVersion : Windows Server 2019
TotalLicenses : 14
TypeAndModel : RDS Per User CAL

You can see KeyPackId 3 has the RDS cals we want to reduce, we would use the command:

Invoke-WmiMethod -Class Win32_TSLicenseKeyPack -Name RemoveLicensesWithIdCount -ArgumentList 3,2

This would reduce Keypack 3 by 2 licenses, bringing it to a total of 12.

Unable to access IBM IMM after firmware update

Leave a reply

After updating an ancient IBM System x3200 M3 IMM firmware, attempting to logon gave the following error: “Your session has been terminated due to account deletion, account disabled, session termination, or session inactivity.”

This forum post had the answer in a screenshot. You will need the ASU (older version for this model (v9.64) – you can download this from IBM.

Running the downloaded file extracts the ASU utility to the current directory. Once extracted, open a command prompt and run the following commands (substituting %HOSTIP%, %USERID%, %PASSWORD% with your details):

asu64.exe set IMM.https_service enable –host %HOSTIP% –user %USERID% –password %PASSWORD%

asu64 set IMM.SSL_Server_Enable enable –host %HOSTIP% –user %USERID% –password %PASSWORD%

asu64 rebootimm –host %HOSTIP% –user %USERID% –password %PASSWORD%

(The full IMM documentation is here)

You should now be able to access the IMM over HTTPS.

From what I can determine, the firmware update changes something with HTTP and cookies, and HTTPS was not enabled on the original IMM firmware.

Exchange connectivity test fails when certificate doesn’t match name

Leave a reply

I had a scenario where I was using a single name SSL certificate which was setup for mail.domain.test. I needed to get autodiscover to work for this domain name. The DNS host was Godaddy.

I configured an SRV record as follows:

The target pointed to the certificate name. EG: mail.domain.test. This allowed the https://testconnectivity.microsoft.com test to go through.

Set AD Dial in Options for VPN via Powershell

Leave a reply

We had a customer that used the “dial in” options in AD to determine whether or not the users were allowed to use a VPN. They didn’t want to change this to use groups or NPS.

The following powershell allowed us to set this policy based on a group:

$users=get-adgroupmember “Remote_users”

foreach ($user in $users)

{

set-aduser $user -replace @{msnpallowdialin=$TRUE}

}
