Working with Snapshots on the ESXi CLI

I love CLI (Command Line Interface).

It gives you control…

So therefore if I work with ESX and snapshotting:

# vim-cmd vmsvc/getallvms
To get all VM’s andthier ID’s

# vim-cmd vmsvc/snapshot.create [ID] [Name]
To create a snapshot

# vim-cmd vmsvc/get.snapshotinfo [ID]
To get full information on snapshots on the VM

# vim-cmd vmsvc/snapshot.revert [ID]
To revert to a snapshot

# vim-cmd vmsvc/snapshot.remove [ID]
To remove a snapshot

# vim-cmd vmsvc/snapshot.removeall [ID]
To remove all snapshots from the VM

Check if Linux File system is Read-Only

If you for some reason think your Linux File System is read-only. Donot trust on the mount command, as it will show you your FS in rw mode.

Following command will show you the Read-Only mounted File Systems:

 egrep " ro,|,ro " /proc/mounts

A File System can becom Read-Only if it has been away to lang for the OS. To prevent data Corruption, Linux makes it RO.

Cisco AnyConnect “Failed to initialize connection subsystem”

  • 1. Close the Cisco AnyConnect Window and the taskbar mini-icon
  • 2. Right click vpnui.exe in the “Cisco AnyConnect Secure Mobility Client” folder. (I have it in “C:\Program Files (x86)\Cisco\Cisco AnyConnect Secure Mobility Client\”
  • 3. Click on the “Run compatibility troubleshooter” button
  • 4. Choose “Try recommended settings”.
  • 5. The wizard suggests Windows 8 compatibility.
  • 6. Click “Test Program”.  This will open the program.
  • 7. Close
  • Some people may need to repeat the above steps for vpnagent.exe. That is the local service that supports the client user interface.

Newly installed P4330 Lefthand node does not want to join Management group

Today I had to add 2 P4330 nodes to an already existing P4300G2 management group.

Both P4300G2 systems and P4330 systems where on FW level 11.5.
When adding them to the management group an error occurred:

Storage system did not join the management group <GROUPNAME>.
Failed to sync newly added system. Remove the newly added system and try to add it again.

Als the system gave me following error:
“Storage System Status Missing”

Searching the internet I got to a page that indicated that there could be a subnet mask mismatch.
Checking this I came to the conclusion that all was OK. So the “SAN”switches, subnet mask, VLANning.
I made a call with HP.

Seems that some P4x30 systems with FW level 11..5 loaded from the factory have a BUG in the system that gives this result.

So please make sure, if you have this error, you do a Re-Image of the system (keep license key at hand) and re-do the settings you made earlier.
But this will solve your error.

Have Fun!

MSA1040 or MSA2040: Fan’s running full speed

We have had an installation of a MSA 1040 system. At the customer site, we discovered that the FAN’s kept running on full speed.

Current firmware was:  GL105P003

New firmware from HP (released 01 December 2014) fixes this problem (GL200R007).

Hopes this helps you all.

Cleaning Brocarde Switch Zoning

There are moments you need to get the old zoning out of a Brocade SAN switch. This could be, because you are re-using an older switch in your enviroment, or maybe you have been working on your fabric without noticing that you had a Fragmented Fabric.

To clean the config do following steps:


.. and voila!!! A brand new switch.!
