Why DevOps ?

DevOps is a culture/profession which promotes collaboration between Development and Operations Team to deploy code to production faster in an automated & repeatable way. The word 'DevOps' is a combination of two words 'development' and 'operations.'
DevOps helps to increases an organization's speed to deliver applications and services. It allows organizations to serve their customers better and compete more strongly in the market.
In simple words, DevOps can be defined as an alignment of development and IT operations with better communication and collaboration. 





DevOps = ACCELERATE  software delivery  +  BALANCE speed, cost, quality & risk + REDUCE time to customer feedback

A collaborative DevOps implementation can bring real business benefit:
  • Meet customer expectations 100%
  • Develop new applications for new markets
  • Reduce the cost of IT overhead
  • Enable innovation at a controlled cost
  • Reduce the cost of market entry
  • Lower the risk of software change





Horizon Desktop-as-a-Service Platform ( Vmware DaaS )



Desktop as a Service provides a useful solution that can bring greater flexibility, ease of administration and cost savings to organizations.

A third party hosts the back end of a virtual desktop infrastructure (VDI) deployment.


With DaaS, on the other hand, organizations pay no upfront costs. They only pay for the virtual desktops they use each month. Over time, however, these subscription costs can add up and eventually be higher than the capital expenses of deploying on-premises VDI.




Please message me with your problem or what you want before you order

Do you have a problem with your VMware ESXi Host System or a VMware vCenter?

I will help with your problems for the following systems:
  •  vCenter & ESXi Host System

I will help you to manage your virtual server within:
  • vCenter & ESXi Host System

Do you want to try out VMware ESXi on your dedicated server?
If yes I can help you with the installation or if you want to install it for you :)

Thanks

Solaris 10 ssh lock after retires policy

Check :-

bash-3.2# cat /etc/security/policy.conf | grep LOCK_AFTER_RETRIES=NO
#LOCK_AFTER_RETRIES=NO
bash-3.2# cat /etc/security/policy.conf | grep LOCK_AFTER_RETRIES
# LOCK_AFTER_RETRIES specifies the default account locking policy for local
#LOCK_AFTER_RETRIES=NO
bash-3.2#

Apply :- 


bash-3.2# cp /etc/security/policy.conf /etc/security/policy.orig
bash-3.2#
bash-3.2#
bash-3.2# echo "LOCK_AFTER_RETRIES=YES" >>  /etc/security/policy.conf
bash-3.2#
bash-3.2# cat /etc/security/policy.conf | grep LOCK_AFTER_RETRIES
# LOCK_AFTER_RETRIES specifies the default account locking policy for local
#LOCK_AFTER_RETRIES=NO
LOCK_AFTER_RETRIES=YES

Now if you have appply the rule below, it should work .. 

bash-3.2# cat /etc/default/login | grep RETRIES
# login will wait after RETRIES failed attempts or the PAM framework returns
# RETRIES determines the number of failed logins that will be
# will be locked if failed logins equals or exceeds RETRIES.
RETRIES=5
bash-3.2#

How to Enable the Audit Service in Solaris

cd /etc/security

# ./bsmconv
This script is used to enable the Basic Security Module (BSM).
Shall we continue with the conversion now? [y/n] y
bsmconv: INFO: checking startup file.
bsmconv: INFO: turning on audit module.
bsmconv: INFO: initializing device allocation.

The Basic Security Module is ready.
If there were any errors, please fix them now.
Configure BSM by editing files located in /etc/security.
Reboot this system now to come up with BSM enabled.
Reboot:
# init 6
After the reboot, the SMF service: svc:/system/auditd:default will be in online status and the auditd daemon will be running:
# svcs -l auditd
fmri         svc:/system/auditd:default

LUN Recovery procedure in Solaris

LUN Recovery procedure in Solaris  

Lun discovery using Solaris :-

#sudo mpathadm list lu
#sudo luxadm -e forcelip /dev/cfg/c1
#devfsadm -Cv
#cfgadm -al

Best Practice Before Removing LUN(s) and/or Target(s) From a Solaris Server:-

cfgadm -o unusable_FCP_dev -c unconfigure c #::WWPN (for Solaris 8/9 and above)
or

cfgadm -o unusable_SCSI_LUN -c unconfigure c #::WWPN (for Solaris 10 and above)

ProcedureTo Configure Auto-Failback for a Particular Multipathing Support
Symmetrical devices allow for automatic failback to a possible optimal path. If a failover occurs on the initial path, the standby path becomes the new online path. Usually the standby path is a suboptimal path. When auto-failback is enabled, the initial path comes back online, failover to the initial path automatically occurs.

Run the mpathadm list mpath-support command.


# mpathadm list mpath-support
mpath-support: libmpscsi_vhci.so

Select an mpath support name from the output list.

Run the mpathadm modify mpath-support -a [on | off] mpath-support-name command.


# mpathadm modify mpath-support -a off libmpscsi_vhci.so

Run the mpathadm show mpath-support mpath-support-name command to check the change.

Note –
The auto-failback display initiated by the mpathadm modify command setting is effective while the system is running. However, to keep the changed setting persistent, you must update the /kernel/drv/scsi_vhci.conf file. Refer to Configuring Automatic Failback.

ProcedureTo Fail Over a Logical Unit
This operation is applicable only to devices in the following two categories:

Asymmetric devices with a proprietary failover mechanism recognized and supported by multipathing support

Devices conforming to the T10 Standard Target Port Group Support libmpscsi_vhci.so and providing explicit mode asymmetric logical unit access

Run the mpathadm list lu command.
