Configuration

Set up HPE XP storage

You need to specify settings as described below for storage systems. For details about each setting, see the user's guide of the storage systems.

1. User accounts

   Create a storage device account belonging to the Administrator User Group.

2. THP pool

   Create a THP pool that is used by the driver.

3. Ports

   Enable Port Security for the ports used by the driver.

Set up HPE XP storage volume driver

Set the volume driver to HPE XP block storage driver by setting the volume_driver option in the cinder.conf file as follows:

If you use Fibre Channel:

[hpe_xp]
volume_driver = cinder.volume.drivers.hpe.xp.hpe_xp_fc.HPEXPFCDriver
volume_backend_name = hpexp_fc
san_ip = 1.2.3.4
san_login = hpexpuser
san_password = password
hpexp_storage_id = 123456789012
hpexp_pools = pool0

If you use iSCSI:

[hpe_xp]
volume_driver = cinder.volume.drivers.hpe.xp.hpe_xp_iscsi.HPEXPISCSIDriver
volume_backend_name = hpexp_iscsi
san_ip = 1.2.3.4
san_login = hpexpuser
san_password = password
hpexp_storage_id = 123456789012
hpexp_pools = pool0
