Batch Get current date as filename
0If you are working with tools that genegates logfiles it is handy to have the name of the logfile based on the date. The following command will help us create a filename based on the system date. The command takes the date, puts it in MMDDYYYY format and appends the .LOG extension. The date with the .LOG extension is assigned to a variable named datefile. For example, today, on July 27, 2007 the datefile variable would contain: 07272007.LOG
The command for setting up the datefile variable is:
for /F “tokens=2,3,4 delims=/ ” %%i in (‘date /t’) do set datefile=%%i%%j%%k.log
If you want to view the contents of the datefile variable, you can do so by using the echo command. Since datefile is a variable, you must place percentage signs on each end of it any time you reference it. For example, the command for viewing the contents of this variable would be:
Echo %datefile%
But we’re not interested in merely viewing the contents of the datefile variable. Our goal is to use the variable’s contents as a filename, and to export eg. the CHKDSK results to the file that is referenced by the datefile variable. To do so, use this command:
Chkdsk > %datefile%
The batch file in its entirety would look like this:
for /F “tokens=2,3,4 delims=/ ” %%i in (‘date /t’) do set datefile=%%i%%j%%k.log Chkdsk > %datefile%
VI3 Configure VMkernel portgroup
1# add VMkernel to vSwitch2
esxcfg-vswitch -A VMkernel vSwitch2
# set ip on Vmkermel
esxcfg-vmknic -a VMkernel -i <ip kernel> -n <sn kernel>
esxcfg-route <gw kernel>
esxcfg-vswitch v 101 p VMkernel vSwitch2
# enable vmotion on the VMkernel portgroup
vimsh -n -e “/hostsvc/vmotion/vnic_set <portgroupName>”
where <portgroupName> is the name of the portgroup that you want to enable vmotion on.
This portgroup name must be the internal portgroup name (as obtained from ‘esxcfg-vswitch -l’ and not the friendly portgroup name.
VI3 Create vSwitch with different number of ports
When using the sc command ‘esxcfg-vswitch -a vSwitch1′ the created switch has the default of 64 ports.
To create a vSwitch with more or less ports, add ‘:<no ports>’ to the name of the vSwitch.
Resulting command: ‘esxcfg-vswitch -a vSwitch1:128′ to create a vSwitch with 128 ports.
Note: Viewed from ‘esxcfg-vswitch -l’ the Num ports is 64, when viewed from VI client the vSwitch properties gives 56.
