Allocating Luns from VMAX has a different method and its not like that in DMX. Here comes something new called Port-group, storage-group, initiator-group and a masking view
Initiator Group : Its a group which consists of
Host HBA wwn
Port Group : Its a group which consists of
front end ports of the array
Storage Group : Its a group which consists of all the luns that need to be assigned to host
Masking view : Its a view created with a port-group, Initiator group and storage group
When we want to allocate luns to host, we create a masking view for it..
Entire host-storage communication takes place through this masking view
Below i have mentioned on creation and deletion of Port Group,Storage Group, Initiator Group & Masking view.
*********************************************************************************
INITIATOR GROUP CREATION
***************************
The initiator group name i am going to create is ig_libg162 which consists of 2 HBA wwn no.
1) Check if the host WWN no. is visible in the Symmetrix at the ports that is zoned from the
switch end. Here i have zoned it to ports 7e:1 and 8g:1
bash-3.2# symaccess list logins -dirport 7e:1 -sid 016

*************************************************************
2) Select the particular WWN no. required and create the initiator Groups with the command given
below. Check if the initiator group is created and the required wwn no. got added or not.
bash-3.2# symaccess -sid 016 create -name ig_libj162 -type initiator -wwn 210000e08b9472a0
bash-3.2# symaccess -sid 016 show ig_libj162 -type initiator

DELETING INITIATOR GROUP
*****************************
We should first remove the HBA wwn no. first one by one and then we should delete the entire Initiator Group
bash-3.2# symaccess -sid 016 -name ig_libj162 -wwn 210000e08b9472a0 remove -type initiator

*********************************************************************************
CREATING PORT GROUP
************************
Here i am going to create a port group with Symmetrix Front End ports 7e:1 and 8g:1
1) first check which all ports are used and what all are the port names given
bash-3.2# symcfg -sid 016 list -fa all
Symmetrix ID: 000194901016

******************************************
2) Create port group using the command mentioned below and check if the port got added or not.
bash-3.2# symaccess -sid 016 create -name pg_7e1_8g1 -type port -dirport 7e:1
bash-3.2# symaccess list -sid 016 -type port

3) Add the required ports to this port group depending upon the reliability u need using the
below command.
bash-3.2# symaccess -sid 016 -name pg_7e1_8g1 -type port -dirport 8g:1 add
bash-3.2# symaccess -sid 016 show pg_7e1_8g1 -type port

*********************************************************************************
DELETING PORT GROUP
************************
We should first remove the front end ports one by one and then we should delete the entire Port Group.
bash-3.2# symaccess -sid 016 -name pg_7e1_8g1 -type port -dirport 7E:1 remove
bash-3.2# symaccess -sid 016 show pg_7e1_8g1 -type port

*********************************************************************************
CREATING STORAGE GROUP
****************************
Here i am creating a storage group with 25 Luns of 5 Gb size each.
1) Add a storage group using a device as shown with the below command and check if the devices
are visible in the storage group
bash-3.2# symaccess -sid 016 create -name sg_libj162 -type storage dev 0087
bash-3.2# symaccess -sid 016 show sg_libj162 -type storage
Symmetrix ID : 000194901016
Storage Group Name : sg_libj162
Last updated at : 02:54:22 PM on Fri Aug 31,2012
Number of Storage Groups : 0
Storage Group Names : None
Devices : 0087
Masking View Names
{
None
}
***************************************
2) After this u can keep on adding devices to the storage group depending on the requirement using the below command
bash-3.2# symaccess -sid 016 add devs 0088:009F -name sg_libj162 -type storage
bash-3.2# symaccess -sid 016 show sg_libj162 -type storage
Symmetrix ID : 000194901016
Storage Group Name : sg_libj162
Last updated at : 02:57:37 PM on Fri Aug 31,2012
Number of Storage Groups : 0
Storage Group Names : None
Devices : 0087:009F
Masking View Names
{
None
}
*********************************************************************************
DELETING STORAGE GROUP
****************************
In Similar way like what we did for port group and initiator group, remove the luns first from the storage group and then delete the storage group
1) bash-3.2# symaccess -sid 016 remove devs 0087:009F -name sg_libj162 -type storage
bash-3.2# symaccess -sid 016 show sg_libj162 -type storage
Symmetrix ID : 000194901016
Storage Group Name : sg_libj162
Last updated at : 02:59:55 PM on Fri Aug 31,2012
Number of Storage Groups : 0
Storage Group Names : None
Devices : None
Masking View Names
{
None
}
****************************************************************
2) Delete the storage group as shown with the below command
bash-3.2# symaccess -sid 016 delete -name sg_libj162 -type storage
Delete Storage group 'sg_libj162' (y/[n])? y
*********************************************************************************
CREATING MASKING VIEW
**************************
1) Create the masking view with the proper storage group in which all the luns are added, with
the port group where all the ports are added and with the initiato group where all the HBA wwn
no.s of the hosts are added. as shown in the below command
bash-3.2# symaccess -sid 016 create view -name mv_libj162 -storgrp sg_libj162 -portgrp
pg_7e1_8g1 -initgrp ig_libj162
bash-3.2# symaccess -sid 016 show view mv_libj162
