'''ESX'''

* Shutdown a host ready for power off  

** <code> /bin/host_shutdown.sh </code>

* Stop HA...

** <code>  /etc/init.d/VMWAREAAM51_vmware stop  </code>

** <code>  /etc/init.d/VMWAREAAM51_vmware start  </code>

'''ESX'''

<pre>

<code> services.sh restart </code>

<pre>

service vmware-webAccess restart

</pre>

On the ESX that currently owns the VM...

# Get the VM's config file path

#* <code> less \vm_path\vmware.log </code>

To put the ESX into maintenance mode with no access from the Infrastructure Client (VCP) use the following commands - use with caution

Basic network sniffer available in Service Console

In order to be able to change a user (or root) password to one that breaches password complexity checking

#* <code> esxcfg-auth --usepamqc=-1 -1 -1 -1  8 8 </code>

You might need to regenerate certificates if

* Change ESX host name

* '''ESX4'''

** <code> ethtool -i vmnic<no> </code>

** Where <code><no></code> is your NIC no, eg <code> vsish -e get net/pNics/vmnic1/properties </code>

The new LUN needs to be carved up and presented to all ESX's that should see it (normally all ESX's from a particular cluster).  Once completed, follow the procedure below to add to the ESX's...

# Pick ESX in cluster with lowest load

# On the remaining ESX's, go to '''Storage Adapters''', hit '''Rescan...''' (leave both boxes checked)

The SAN LUN ID is used by SAN admin's to identify LUN's.  It's not readily available from the GUI and has to be extracted from the vml file...

So the SAN LUN ID is <code> 60060160c6931100cc319eea7adddd11 </code>

Doesn't require Emulex HBA utility to be installed

# <code> cd /proc/scsi/lpfc </code>

</pre>

Can be found at [http://www.emulex.com/vmware/support/index.jsp Emulex Lputil].

#* <code> ./Install.sh </code>

<pre>

Installing Emulex HBAAPI libraries and applications...

Installation of Emulex HBAAPI libraries and utilities is completed.

</pre>

# Download the Driver and Application kit for VMware from [http://www.emulex.com/downloads/emulex/cnas-and-hbas/drivers/vmware/fc-74040-pkg.html Emulex's website].

#* At time of writing the current version of package was <code>elxvmwarecorekit-esx35-4.0a45-1.i386.rpm</code>

#* EG <code> rpm -ivh elxvmwarecorekit-2.1a42-1.i386.rpm </code>

Requires the HBA Utility to be installed 1st (see above)

* '''Using HBA Utility''' (must be installed 1st - see above).  See the Emulex website for the latest version, eg [http://www.emulex.com/ts/downloads/lp1050/lp1050ex.jsp Emulex LP1050Ex]

To update the firmware (example uses LP1050Ex-mf191a5)

# Create folder in /var/updates;

#* <code> mkdir /var/updates/EmulexLP1050Ex-mf191a5 </code>

# Copy the firmware update onto the ESX

# Start the utility (on startup it should detect one or more HBA's;

#* <code> /usr/sbin/lpfc/lputil </code>

#* EG <code>/usr/sbin/hbanyware/hbacmd download 10:00:00:00:c9:82:97:9e zf280a4.all</code>

# Download correct verion from EMC's website

#* At time of writing the current version file was [ftp://ftp.emc.com/pub/emcgrab/ESX/Old_Releases/v1.1/ emcgrab_ESX_v1.1.tar]

# Results can be found in <code>\emcgrab\outputs</code> folder

# <code> cd /proc/scsi/qla2300 </code>

# <code>  more 1 </code> for HBA 1

<pre>

QLogic PCI to Fibre Channel Host Adapter for QLA2340 :

         Firmware version:  3.03.19, Driver version 7.07.04

Installation instructions for the SANsurfer utility

# Uncompress the file with the following command;

#* <code> gunzip scli-1.7.0-12.i386.rpm.gz </code>

See QLogic website for latest version, you must ensure the firmware version is compatible with the current running driver version.  Requires SANsurfer to be installed 1st (see above)

# Create a new folder for the update;

#* <code> mkdir /var/updates/q231x_234x_bios147

# Copy the firmware onto the ESX server;

# Move to the folder containing the update;

#* <code> cd /var/updates/q231x_234x_bios147/ </code>

ESX's don't like to loose the SAN, to the extent that during the scheduled SAN downtime the following is recommended...

# Shutdown ESX's (and hosted VM's) connected to affected storage

# Restart / migrate VM's

'''Netflow is available on ESX v3 only, and is an experimental feature.  Netflow v5 is sent.'''

*# <code> vmkload_mod -u netflow </code>

Logged in as root use the esxcfg-vswif command <code>esxcfg-vswif <options> [vswif] </code>

Note: You set the Service Console VLAN (to 1234) using a similar command to:  <code>esxcfg-vswitch -v1234 -p"Service Console" vSwitch0></code>

# Log into the ESX Server service console as root.  

# Find the desired time zone under the directory /usr/share/zoneinfo
