ESX 4.1 Slow Boot

[arie1]

Hey All,

Since upgrading a few "test hosts" to ESX 4.1 I have very slow boot times. In the past I resolved this by setting the following advanced setting values.

Scsi.ConflictRetries = 20

Scsi.UWConflictRetries = 80

I believe the root cause of this is because we have a MSCS within the VM cluster. Now under ESX 4.1 I don't see these options available anymore, is there an alternative way to resolve this problem? 30min+ boot time isn't really acceptable

Thanks

Hello,

With ESX 4.x you can check the value of ConflictRetries using:

esxcfg-advcfg -g /Scsi/ConflictRetries

(If you upgraded it should have retained the previous value).

You can set a new value using the -s flag instead of -g

This value is also exposed via the GUI (Virtual Infrastructure Client) -- you can see more on this at the following link (including observation from another user who looks to have experienced the same thing you are seeing):

Thanks and good luck,

ok. qlogic driver will take a quite long time to fully init during 4.1 boot, if you have a dual port or two adapters it will take even longer. nothing i am aware of by now you can do about that.

best regards,

Well Well did everyone knows something about patches from vmware witch helps to reduce the boot times in that cases. i saw there are also a lot of probs with netapp devices ;/
