Vmax-host hba question
Hello All,
Need some help on this. We have a server with only one path (one HBA) zoned to VMAX. now the OS group is adding one more HBA to the host. But the question is about at present the configuration is like this.
symaccess -sid xxx list assignment -dev 0D12
Device Identifier Type Dir:P
------ ---------------- ----- ----------------
0D12 10000000c00999 FIBRE FA-8F:1,FA-7F:1
symaccess -sid xxxx list devinfo -ig IG_name
Sym Host Cap Dev Dir:P Physical Device Name Lun Attr (MB) Masking View Name
----- ----- ----------------------- ---- ---- ------ ------------------------
0D12 08F:1 Not Visible 1 34526 V_namehost 7F:1 Not Visible 1 V_namehost
suppose if I zone 7F;1 with the new HBA, what are the steps I need to make on VMAX?
Do I need to unmask all the devices from 7F;1 first, or just add the WWN my guess is.
symaccess -sid 1234 remove -login -wwn 10000000c00999 -dirport 7F:1 and then rename? Please elaborate. What can be done?

Hi,
Since there is no zoning with FA 7F, the wwn wont be login to this hence no need to remove login from 7F;1.Except last step all are fine.

Hi,
You can follow these steps
Once you zone new WWN with 7F:1, Add the new WWN in the existing IG group
symaccess -sid xxxx -type initiator -name initiator_IG -WWN 1xxxxxxxxx add
make sure the LUNs are visible through new HBA from server side.
rename the WWN
symaccess -sid xxxx rename -wwn XXXXXXXXXXXXXXX -alias HOST/HBAX
and If you want to remove the masking of old WWN through 7F:1,delete the zone for that and remove the login

Hi,
what i understood is you are going to add a new HBA and not going to do
anything with existing one.
if you zone new HBA with 7F:1 it will login through only through 7F not
through 8F.
suppose current HBA is 0 and which is logged in through 8F:1 and 7F:1 and
you are adding HBA 1 now.so you will zone it with 7F( assuming you already
done with physical HBA connectivity to the switch port) and it will login
in 7F then you can rename it with above command.

Can you expand on the below statement if I rename the -wwn will it not effect 8F:1??
How can I rename only for 7F:1???
rename the WWN
symaccess -sid xxxx rename -wwn XXXXXXXXXXXXXXX -alias HOST/HBAX

Hi,
Please see the first statment clearly below, 7F;1 and 8F:1 are masked with same WWN, (but zoned only to 8F:1, no zoning for 7F:1)
in this scenario what are the next steps, is that just unmasking devices using the old WWN and 7F:1 will do right?
symaccess -sid xxx list assignment -dev 0D12
Device Identifier Type Dir:P
------ ---------------- ----- ----------------
0D12 10000000c00999 FIBRE FA-8F:1,FA-7F:1
My assumption of steps is as below
Zone the new WWN with 7F:1
Add the new WWn to the existing IG group using following command
symaccess -sid xxxx -type initiator -name nameofig add -wwn
make sure the LUNs are visible through new HBA from server side.
remove the masking as below.
symaccess -sid xxxx remove -login -wwn -dirport 7F:1
