Implement and configure AWS Backup for VMware Cloud on AWS VM workloads

Image
In our previous post we saw the design of the AWS Backup on VMC. In this post we’re going through the implementation steps As per the design and best practice, we are going to use the ENI for the Backup traffic CREATE A VPC ENDPOINT  TO CREATE AN INTERFACE ENDPOINT FOR AN AWS SERVICE 1. Open the Amazon VPC console at https://console.aws.amazon.com/vpc    2. In the navigation pane, choose Endpoints 3. Choose Create endpoint 4. Name the endpoint   5. For Service category, choose AWS services 6. For Service name, search “ Backup ” and select “ backup-gateway ” service from the dropdown 7. For VPC, select the VPC which we used for SDDC deployment and extension 8. To create an interface endpoint for Amazon S3, you must “uncheck” Additional settings, Enable DNS name. This is because Amazon S3 does not support private DNS for interface VPC endpoints 9. For  Subnets , select one subnet per Availability Zone which we used for SDDC VMC selection  10. For Security group , sel

RHEL server LUN paths goes offline during failover




Description of problem:

Client is attempting to kickstart RHEL5 to a blade system with SAN attached
storage. The customer is hitting an issue where anaconda complains with the
following message at the beginning of the install:

On virt console 1:
Warning: /dev/sda is a read-only filesystem and hit OK to continue

On virt console 3:
parted exception: Warning: Unable to open /dev/sda read-write
(Read-only file system). /dev/sda has been opened read-only

The customer has to hit OK to accept this and the installation will then
complete successfully.

There are currently two LUNs presented from the SAN to the host. /dev/sda is
indeed read-only and apparently it is a gatekeeper type device that is
exported/presented to numerous hosts hence why it's read-only. /dev/sdb is the
second LUN device that we want to install to.

I've tried using the following entries in the kickstart file:
ignoredisk --drives=sda
clearpart --all --drives=sdb
partition /boot --fstype=ext3 --size=200 --ondisk=sdb
partition pv.03 --size=1 --grow --ondisk=sdb
<and create vg and lv......>

And removing the zerombr reference but the customer is still hitting the issue.

How reproducible:
1. Install via kickstart or manual
2. Kickstart profile uses 'ignoredisk=sda' to ignore first LUN
3. Still prompted by anaconda that sda is read-only
4. Hitting Ok or Ignore will continue the installation
Version-Release number of selected component (if applicable):

Steps to Reproduce:
1. Install via kickstart or manual
2. Kickstart profile uses 'ignoredisk=sda' to ignore first LUN
3. Still prompted by anaconda that sda is read-only
4. Hitting Ok or Ignore will continue the installation

Actual results:
User prompted to hit OK when /dev/sda device is found to be read-only

Expected results:
ignoredisk directive in kickstart should indicate which devices to ignore and
not present a warning that it's read-only.

HOW TO EDIT THE BCD REGISTRY FILE

Image
The BCD registry file controls which operating system installation starts and how long the boot manager waits before starting Windows. Basically, it’s like the Boot.ini file in earlier versions of Windows. If you need to edit it, the easiest way is to use the Startup And Recovery tool from within Vista. Just follow these steps: 1. Click Start. Right-click Computer, and then click Properties. 2. Click Advanced System Settings. 3. On the Advanced tab, under Startup and Recovery, click Settings. 4. Click the Default Operating System list, and edit other startup settings. Then, click OK. Same as Windows XP, right? But you’re probably not here because you couldn’t find that dialog box. You’re probably here because Windows Vista won’t start. In that case, you shouldn’t even worry about editing the BCD. Just run Startup Repair, and let the tool do what it’s supposed to. If you’re an advanced user, like an IT guy, you might want to edit the BCD file yourself. You can do this

DNS Scavenging.

                        DNS Scavenging is a great answer to a problem that has been nagging everyone since RFC 2136 came out way back in 1997.  Despite many clever methods of ensuring that clients and DHCP servers that perform dynamic updates clean up after themselves sometimes DNS can get messy.  Remember that old test server that you built two years ago that caught fire before it could be used?  Probably not.  DNS still remembers it though.  There are two big issues with DNS scavenging that seem to come up a lot: "I'm hitting this 'scavenge now' button like a snare drum and nothing is happening.  Why?" or "I woke up this morning, my DNS zones are nearly empty and Active Directory is sitting in a corner rocking back and forth crying.  What happened?" This post should help us figure out when the first issue will happen and completely avoid the second.  We'll go through how scavenging is setup then I'll give you my best practices.  Scavenging s

AD LDS – Syncronizing AD LDS with Active Directory

Image
First, we will install the AD LDS Instance: 1. Create and AD LDS instance by clicking Start -> Administrative Tools -> Active Directory Lightweight Directory Services Setup Wizard. The Setup Wizard appears. 2. Click Next . The Setup Options dialog box appears. For the sake of this guide, a unique instance will be the primary focus. I will have a separate post regarding AD LDS replication at some point in the near future. 3. Select A unique instance . 4. Click Next and the Instance Name dialog box appears. The instance name will help you identify and differentiate it from other instances that you may have installed on the same end point. The instance name will be listed in the data directory for the instance as well as in the Add or Remove Programs snap-in. 5. Enter a unique instance name, for example IDG. 6. Click Next to display the Ports configuration dialog box. 7. Leave ports at their default values unless you have conflicts with the default values. 8. Click N
