Load balancing: Keep the
following HP-UX native
multipathing parameters at
their default values:
●
load_bal_policy

Temporarily disable UNMAP
during file systems creation
(only when using Veritas
Volume Manager):
●
To temporarily disable
UNMAP for the targeted
device on the host (before
file system creation):
#vxdisk set
reclaim=off "disk

●
To re-enable UNMAP for
the targeted device on
the host (after file system
creation):
# vxdisk reclaim
"disk name"

Boot from SAN
For guidelines and recommendations for boot from SAN with HP-UX hosts and PowerStore, refer to the
Considerations for Boot
from SAN with PowerStore
appendix.
Fibre Channel Configuration
This section describes the recommended configuration that should be applied when attaching hosts to PowerStore cluster using
Fibre Channel.
NOTE:
This section applies only to Fibre Channel.
NOTE:
PowerStore supports only FC-SW FCP connections. GigE iSCSI and FC direct connections from HP-UX initiators to
PowerStore target ports are not supported.
NOTE:
Before you proceed, review
Fibre Cannel and NVMe over Fibre Channel SAN Guidelines
.
Pre-Requisites
This section describes the pre-requisites for FC HBA configuration
●
Refer to the E-Lab Interoperability Navigator (
) for supported FC HBA models and drivers.
●
Verify all HBAs are at the supported driver, firmware and BIOS versions.
●
For instructions about installing the FC HBA and upgrading the drivers or the firmware, see HP documentation.
