HP SAN Virtualization Services Platform - Manual (Page 215)

Description Property
The current status of the host. Possible values:
• Present—For VSM servers, this indicates that the host is polling to the active
VSM server through all the HBAs associated with the host. For other hosts, this
indicates that the DPMs report that all HBAs associated with this host are re-
cognized and active.
• Degraded—For VSM servers, this indicates that the host is not polling through
all the HBAs associated with this host. However, the host is polling properly
through at least one HBA. For other hosts, this indicates that the DPMs are not
discovering all the HBAs associated with this host. However, the host has at
least one HBA that is discovered properly.
• Failed—For VSM servers, this indicates that the HBAs associated with the host
are recognized on the fabric but the host is not polling through any of them.
This means that the host and the active VSM server are not communicating.
For other hosts, this indicates that all the DPMs that support the host are not
communicating with the active VSM server. The host inherits the failed status
of the DPMs that support it.
• Absent—This indicates that all the HBAs associated with the host are no longer
visible on the fabric. For VSM servers, this status is reported in the discovery
results of the VSM server. For other hosts, this status is reported in the discovery
information provided by DPMs.
• Offline—A user has moved the host into offline status. For information about
offline status, see “
Managing host online/offline state ” on page 157.
Status
The type of access permission assigned to the host. Possible values:
• Full—The host has read/write access to the snapshot.
• Read—The host has read-only access to the snapshot.
• None—The host has no access to the snapshot.
Permission
The Logical Unit Number (LUN) that the DPM uses to expose the snapshot to the
host, if the host is a UDH.
LUN
Snapshot information—Data Path Module/VSM tab
If the selected snapshot is presented to a UDH host, the Data Path Module/VSM tab shows which
DPM is the primary DPM for presenting the snapshot to the host and which DPM is currently active.
Table 94 Snapshot Data Path Module/VSM tab fields
Description Property
The name of each DPM that services the snapshot. Data Path Module
The status of the DPM. Possible values:
• —Present status. The DPM is polling to the active VSM server through all the
HBAs associated with the DPM.
• —Degraded status. The DPM is not polling through all the HBAs associated
with the DPM. However, the DPM is polling properly through at least one HBA.
• —Failed status. The HBAs associated with the DPM are recognized on the
fabric but the DPM is not polling through any of them. This means that the DPM
and the active VSM server are not communicating.
• —Absent status. This indicates that all the HBAs associated with the DPM are
no longer visible on the fabric.
