Setting the FA port flags for a VMware host on DMX-4

Question

Hi my name is Eric Cortes From Ixe Bank in Mexico City

I have a FA in the Symmetrix DMX 4, and I want to configure it for a Vmware host, I found a procedure to do that, but i am not sure that it is ok.

Could you any one to check my script on order to configure de FA for a Vmware host?

the script is as follows.

PortFlags.txt
# SC3-Bit, if it needs setting,required for Enginuity 5669 to 5670:
set port 01C:0 scsi_3=enable;
# SP-2-Bit, if it needs setting,required for ESX Server v3.0:
set port 01C:0 SPC2_Protocol_Version=enable;
#End of command file

symconfigure -sid 766 -f PortFlags.txt -v preview
symconfigure -sid 766 -f PortFlags.txt -v prepare
symconfigure -sid 766 -f PortFlags.txt -v commit

Thanks in advance

Best regards

This is the 'good old way' .. This will change the whole port and modify behaviour for every host connected to the affected ports (01C:0 in your example) ..With recent codes (and DMX4 have a recent code ) you can also use symmask command and modify behaviour only for some WWNs thus allowing cohexistence of old hosts and new VMWARE3 infrastructure.There is also a document somewhere on powerlink explaining how to introduce SPC2 flag (but will work for every other flag) in an existing vmware infrastructure being upgraded.

Just to emphasis Stefano's remark - changing the SPC2 bit requires an outage if this is an existing VMWare host as the addressing changes.

If you have not already you should check out the following paper: "Enabling SPC-2 Compliancy on EMC Symmetrix DMX Devices Connected to VMware VI3 Environments - Applied Technology"

You can set the flags using the symmask command. You need Solutions Enabler 6.4 and you can issue the following: This is for ESX 3.x

symmask -sid Symmid -wwn xxx set hba_flags on C,SC3, SPC2 -enable -dir <#> -p <#>

This will enable all the flags for ESX 3.x and the FA port your ESX host hba is connected to.
