Transitioning to Auto-Provisioning Groups

Auto-provisioning groups look to replace the traditional symmasking functionality and definitely simplifies the provisioning process.

3 Grouping Objects

  • Storage groups: symaccess -sid 1234 create -type storage -name mystorage -devs 050:053
  • Port groups: symaccess -sid 1234 -type port -name myports -dirport 7e:0, 8:e0
  • Initiator groups: symaccess -sid 1234 create -type initiator -name myinit -file initiator_list

Must define a masking view

  • Associates devices in the storagr group to the port groups to the intiator group
  • Uses dynamic lun addressing, same lun address for all paths
  • symaccess -sid 1234 create view -name dbserver -storgrp mystorage -portgrp myports -initgrp myinit
  • Simplifies updates/changes

AccessLogix Database

  • ACLX gatekeeper device (instead of the VCM database)

Limited symmask Compatibility Mode

  • Both the VCM and ACLX database contain masking entires, resides in SFS, accessed through gatekeeper device
  • However, data structures are completely different
  • VCM database entries are based on one-to-one relationship between initiators and front-end ports
  • ACLX database entries are based on many-to-many relationship between groups of initiators and ports
  • Compatibility mode will take the traditional VCM symmask command but it still convert it to the auto-provisioning groups above but with one entry in each group
  • Restrictions: once you start using symmask, you have to continue using symmask. If you use symaccess, symmask will no longer work because symmask is looking for one-to-one relationship
  • Best practice is to transition over to auto-provisioning groups

Storage Templates

  • Define capacity, protection, drive type, and other criteria
  • Specify template rather than specific devices when initially provisioning storage or adding new capacity
  • If the devices do not exist, it can optionally create the device
