  • 1.  NetApp Pluggable Storage and Initiator groups (igroups) name

    Posted Fri June 10, 2022 11:35 AM
    Hi all,

    we have PowerVC 1.4.3.x with NetApp storage configured as Pluggable Storage.

    Is there a way to customize igroup name generated by PowerVC in NetApp ?

    here is an example of generated igroup name : openstack-014f85bd-e669-4d5f-9855-6b4a16ca2c15

    Thanks in advance for your help

    1. Netapp added a piece of code here:

    NetApp: Support custom igroups:

    https://github.com/openstack/cinder/commit/1b2742a3d397d67ea989f080d44cc537bdcf1f5a

    but this looks that it's trying to support the custom igroup name created in backend and openstack created igroup name simultaneously.

    2. The way Netapp is generating igroup name in openstack is by combining 'openstack-' and a randomly generated UUID at runtime.

    Reference: https://github.com/openstack/cinder/blob/master/cinder/volume/drivers/netapp/dataontap/block_base.py#L500

    igroup_name = na_utils.OPENSTACK_PREFIX + six.text_type(uuid.uuid4())

    3. PowerVC does not generate igroup name and customization of igroup name should be addressed by Netapp team. Please contact Netapp team for support.

    Even if PowerVC applies a patch or gives a configuration option to override igroup_name, it might affect other use-cases within the Netapp storage.

    @Sylvain)) Is it possible to share the config file used in registering Netapp as pluggable storage to PowerVC ? ​
