Storage Allocation from Symmetrix DMX-4 to Windows host using symcli
Prerequisites:
- First Collect the WWN numbers of windows host from the windows administration team.
Procedure
- Login into the storage management server.
- Execute symcfg discover and symmask refresh commands to refresh configuration and masking database.
root@DMX-MGMT # symcfg discover This operation may take up to a few minutes. Please be patient... You have new mail in /usr/mail/root root@DMX-MGMT # symmask refresh Refresh Symmetrix FA/SE directors with contents of SymMask database 000290102693 (y/[n]) ? y Symmetrix FA/SE directors updated with contents of SymMask Database 000290102693 root@DMX-MGMT #
- Check host is connectivity status in DMX -4 by executing
symmask list logins –wwn XXXXXXXXXX
root@DMX-MGMT # symmask list logins -wwn 21000024FF29F5D5 Symmetrix ID : 000290102693 Director Identification : FA-4D Director Port : 0 User-generated Logged On Identifier Type Node Name Port Name FCID In Fabric ---------------- ----- --------------------------------- ------ ------ ------ 21000024ff29f5d5 Fibre 21000024ff29f5d5 21000024ff29f5d5 01e5f7 Yes Yes root@DMX-MGMT #
- If host or server is connected to DMX-4 properly, check to which port it is connected and note down port number. In this scenario host is connected to director 4D and port 0.
- Now we create devices (LUNS) to allocate to host. Most of the environments devices are already created.
- To check free devices (which are not allocated to any host).

- Note down free device IDs
- Now we need to map devices to FE port to which host is connected/zoned (Noted port number in previous step).
- To map the devices we need check for available LUN IDs on the FE port.
- To check available LUN IDs on the FE port please execute following command

- Check the output. In output, available LUN addresses are marked with star(*).
- Addresses marked with star and its next addresses are available LUN IDs in HEXA decimal format.
- The maximum devices can be allocated to window server are 256. Because of this limitation, server cannot see the LUN addresses greater than 256(FF– in hexa decimal format).
- It is mandatory to choose LUN addresses below 0FF.
- In above example 087 is marked with star. So from 087,088,089………..0A7 are available LUN address for mapping new devices and are less than 0FF.
- Now, command to map new devices to FE port is
map dev “dev ID” to dir “director:port” target=0, lun=”available LUN ID”;
To map all devices to FE ports, create a text file with name map_693 by using VI editor and insert the mapping commands for all devices in the file.
map dev 8DC9 to dir 4d:0 target=0 , lun=087; map dev 8DD1 to dir 4d:0 target=0 , lun=088; map dev 8DD9 to dir 4d:0 target=0 , lun=089; map dev 8DE1 to dir 4d:0 target=0 , lun=08A; map dev 8DE9 to dir 4d:0 target=0 , lun=08B; map dev 8DF1 to dir 4d:0 target=0 , lun=08C; map dev 8DF9 to dir 4d:0 target=0 , lun=08D; map dev 8E01 to dir 4d:0 target=0 , lun=08E;
- Execute the text file (map_693) by using symconfigure command.

- Once mapping completed successfully now we need to do mask new devices to host to make devices visible to server.
- To mask devices execute following commands.
Symmask -sid XXX –wwn XXXXXXXXXXX –dir XX –p 0 add devs “devices IDs”
