Reset the password on a Dell EqualLogic Storage Array

This is just copy from original article at:
http://www.vmguru.nl/wordpress/2010/03/resetting-the-grpadmin-password-on-a-dell-equallogic-san/

If you really don’t know the password set on the grpadmin but still have physical access to it you can start a recovery procedure to reset the grpadmin account back to the default password: grpadmin.
Important: Because you must power-cycle one group member as part of the password reset procedure, volumes with data stored on that member will be unavailable and active iSCSI connections to those volumes will be lost until the member is restarted. You may want to warn users of any impending offline volumes and iSCSI disconnections before resetting the password.
To temporarily reset the grpadmin account password to the default factory-set password, follow these steps:
1.) On one group member, connect the appropriate serial cable to serial port 0 (the correct cable will be different on different models of the PS Array) on the active control module. The active control module is indicated by the green control module status LED labeled ACT. The status LEDs are located on the controllers sometimes on the left side or next to the serial port on other controllers.
2.) Turn off power to the member (if you have dual power supplies, turn off both power supplies). Volumes with data located on the member will be offline and iSCSI connections to those volumes will be lost until the member is restarted.

3.) If the member has two control modules, after it is shut down, remove the controller that your serial cable is not connected to. This is to ensure that, while you are setting password-recovery mode on one controller, the other controller doesn’t run past us and start the array up.  Controllers just have to be removed a little so they don’t make contact any more to be disabled. (2 cm out is far enough)
4.) Turn on power to the member by turning on all the power supplies.
5.) While the member is restarting, press Ctrl/p when the following message appears on the console: Press Ctrl/p to enter setup mode. This will halt the boot process and allow you to enter commands to the boot monitor.
6.) At the CFE> prompt, enter the following commands, which are case-sensitive and must be typed exactly as shown:
CFE> setenv RESETPASSWORD 1
CFE> reload
7.) When the member restarts, the PeerStorage login prompt appears. After a short pause, the following message should appear: WARNING:Password recovery mode… Temporarily resetting grpadmin password.
If you get the previous message, log in the the group using the grpadmin account and its factory-set password, grpadmin:
Login: grpadmin
Password: grpadmin
At this point, you are logged in to the group with read-write permission and can perform any group administration task. At this point, you should set the grpadmin account password to a known value. Use the procedure described in the Modifying Accounts section in the Group Administration manual or use the following command:
> account select grpadmin passwd
Enter New Password: xxxxxxx
Retype password: xxxxxxx
Note: Unless you set the grpadmin account password within five minutes after the password recovery mode message appears, the grpadmin password will revert back to the value it had prior to the password reset procedure (that is, you will no longer be able to log in with the factory-set password).
However, as long as you remain logged in to the grpadmin account, you can set the password to a known value. If the password recovery mode message does not appear, the password reset procedure did not succeed (for example, because you did not enter the CFE commands exactly as shown). In this case, allow the member to completely start up, and then retry the password reset procedure, shutting down the member and following the steps above.
8.) If the member has two control modules, after logging in to the group and setting the grpadmin password, reinsert the second controller,  this restarts the secondary control module and allows it to be used. Within one minute, you should see a console message, indicating that the secondary control module is operational.

PowerConnect 8024-k : link is up even the switch is power cycled or reloaded

“The below is from the release notes for 4.2.2.3 (listed under the 4.2.1.3 section):

Internal ports are up during most of the switch POST Internal ports were up while switch is booting, this was causing traffic loss in network.

Corrected the initialization of the internal ports. CPLD Code Update is required.

1. Update the CPLD using the command 'dev cpldUpdate'

2. Power cycle the switch. (Power Cycle from CMC WebUI. Do not run “reload” from the console prompt)

Converting between CPU RDY summation and CPU % ready values

http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2002181

To convert between the CPU ready summation value in vCenter's performance charts and the CPU ready % value that you see in esxtop, you must use a formula.
The formula requires you to know the default update intervals for the performance charts. These are the default update intervals for each chart:

• Realtime: 20 seconds
• Past Day: 5 minutes (300 seconds)
• Past Week: 30 minutes (1800 seconds)
• Past Month: 2 hours (7200 seconds)
• Past Year: 1 day (86400 seconds)

CPU ready %

To calculate the CPU ready % from the CPU ready summation value, use this formula:
(CPU summation value / ([chart default update interval in seconds] * 1000)) * 100 = CPU ready %
Example: The Realtime stats for a virtual machine in vCenter might have an average CPU ready summation value of 1000. Use the appropriate values with the formula to get the CPU ready %.
(1000 / (20s * 1000)) * 100 = 5% CPU ready

CPU ready summation value

To convert the CPU ready % into a CPU ready summation value, reverse the calculation and use this formula:
(CPU ready % / 100) * ([chart default update interval in seconds] * 1000 = CPU summation value
Example: If a virtual machine has a CPU ready % of 5m, its CPU ready summation value on the Realtime performance chart is calculated like this:
(5 / 100) * 20s * 1000 = 1000 CPU ready

VMware vSphere 5 - Cluster Resource Allocations

Total capacities

Cluster Resource Allocation "Memory - Total Capacity" is "Total Cluster Memory" (what you see in Summary Tab) minus approx. 2576MB of RAM reserved for each ESX host.

So if I have two ESX hosts each with 8GB physical RAM I can see 16GB Total Cluster Memory in Summary Tab. However I have two ESX hosts which has together reserved 2 x 2576MB which is approximately 5GB of memory reservations. So in Cluster Resource Allocation I have 16GB-5GB which is around 11GB of RAM.

The same should apply to Cluster Resource Allocation "CPU - Total Capacity". Each ESX host has reservation of 2341 MHz.

So if I have two ESX hosts each with 10.636 GHz  I can see 21GHz Total Cluster CPU Resources in Summary Tab. However I have two ESX hosts which has together reserved 2 x 2421MHz which is approximately 4.8GHz of CPU reservations. So in Cluster Resource Allocation I should have 21GHz-4.8GHz which is around 16.2GHz. But during my tests I see there 18.4GHz which looks like only one ESX host reservations are subtract. What is the magic and why? Can someone comment it bellow the article?

If you want to know what amount of MEMORY and CPU reservations are reserved for particular ESX hypervisor component you can select some ESX host in the cluster and go to Configuration->System Resource Allocation and switch from simple to advanced view. You have to go through all components and sum all CPU and MEMORY reservations.

Reserved capacities

Cluster Allocation "Reserved Capacity" is sum of reservations of virtual machines and resource pools. Sometimes people are confused and surprised that reserved capacity is very high. That's usually because HA cluster is enabled and fail-over capacity is also reserved and not available for use.

So if I have two node cluster with N+1 redundancy and at least one protected VM is running then half of cluster capacity is reserved by HA.

VMware - Software and Hardware Techniques for x86 Virtualization

In the early days of x86 virtualization, uniformity ruled: all CPUs implemented essentially the same 32-bit architecture and the virtual machine monitor (VMM) always used software techniques to run guest operating systems. This uniformity no longer exists. CPUs today come in 32- and 64-bit variants. Some CPUs have hardware support for virtualization; others do not. Moreover, this hardware support comes in multiple forms for virtualizing different aspects of the x86 architecture.  This document describes the x86 architecture from a virtualization point of view, relating critical architectural features to the major releases of VMware ESX. The goal is to provide, for each version of VMware ESX, an understanding of:

* Which CPU features are required
* Which CPU features can be utilized (but are not required)
* Which CPU features can be virtualized—that is, made available to software running in the virtual machine

With a better understanding of how CPU features are required, used, and virtualized by VMware ESX, you can reason more precisely about what can be virtualized, what performance levels may result for a given combination of CPU, guest operating system, and version of VMware ESX, and how workloads may respond to adjusting configuration parameters both for software running in the virtual machine and at the VMware ESX level.

VAAI

The following outputs shows that Hardware Acceleration is enabled on ESX to take advantage of the storage primitives on ESX 4.1 and ESXi 5.x. Use the esxcfg-advcfg command to check that the options are set to 1 (enabled):

# esxcfg-advcfg -g /DataMover/HardwareAcceleratedMove
# esxcfg-advcfg -g /DataMover/HardwareAcceleratedInit
# esxcfg-advcfg -g /VMFS3/HardwareAcceleratedLocking

To check if the storage array supports VAAI primitives, you can use the following command:

esxcli storage core device vaai status get -d naa.60a98000572d54724a346a6170627a52
VAAI Plugin Name: VMW_VAAIP_NETAPP

Fundamentals of vSphere Performance Management

http://www.doublecloud.org/2010/03/fundamentals-of-vsphere-performance-management/

Performance monitoring is a critical aspect of vSphere administration. This article introduces you the basic concepts and terminologies in vSphere performance management, for example, performance counters, performance metrics, real time vs historical statistics, etc. Much of the content is based on my book VMware VI and vSphere SDK by Prentice Hall.
Once you understand these basics, the related tools and APIs should be relatively easy. If you are already familiar with vSphere Client performance monitoring or esxtop, they help as well.

VMware Health check - RVTools

If you don't have access to VMware Health Check Analyzer then other tool that can be used for VMware health-check engagement is RVTools.  It is free and has been around for about four years.  The author keeps it updated and once you connect to  vCenter or a Host you can export everything directly to an Excel spreadsheet.  The latest version is v3.3 as of April 12, 2012.
