Thanks for the script, very useful.

During my build I dropped the KS.cfg and jumped on the post build configuration. The environment I’m upgrading has a lot of Port Groups leaving a huge scope for error in a mis-type, especially for 17 x ESX 3.5 boxes.

One item I noticed didn’t seem to work on my 3.5 Update 4 was the vMotion enable. From the reading of various blogs it appears the VMware hidden commands change over versions so I’ve included the line from my script here.

I hope this is useful for anyone else choosing the scripting path.

All one line:

vmware-cim-cmd “hostsvc/vmotion/vnic_set” `esxcfg-vmknic -l | grep “VMotion” | awk ‘{print $1}`

Regards,
Darren.

Duncan,

What are the differences between these and is the second command required?

hostsvc/net/refresh
internalsvc/refresh_network

Thanks,

Hugo

Check the SAN Guide for more specific details but in short:
UseDeviceReset and UseLunReset is used for SAN’s. Setting Device to 0 and Lun to 1 results in only that LUN’s SCSI reservations being reset instead of the complete device. This is recommended for SAN’s cause there will be several hosts connected to the same system. Resetting the device could cause disruption in services.

The queuedepth is something that I’ve experienced as in being the best value, and is a generally accepted value. Check the VMTN forum for more info on this.

Thanks for posting this. I spent quite a few hours sorting out a proper .cfg file. But I was wondering if you could explain the reason you included these lines:

# set uselunreset enabled and devicereset disabled
/usr/sbin/esxcfg-advcfg -s 0 /Disk/UseDeviceReset
/usr/sbin/esxcfg-advcfg -s 1 /Disk/UseLunReset

# set queuedepth for qlogic adapter
/usr/sbin/esxcfg-module -s ql2xmaxqdepth=64 qla2300_707_vmw.o

We use qlogic adapters in our blade servers and I didn’t know optimal depth was 64.

May I introduce you to perl -pie?

# enable SSH root-access
mv /etc/ssh/sshd_config /etc/ssh/sshd_config.old
/bin/sed -e “s/PermitRootLogin no/PermitRootLogin yes/g” /etc/ssh/sshd_config.old > /etc/ssh/sshd_config

becomes:

# enable SSH root-access
perl -p -i.old -e “s/PermitRootLogin no/PermitRootLogin yes/g” /etc/ssh/sshd_config
