HP SAN Virtualization Services Platform - Manual (Page 300)

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 group.
• Read—The host has read only access to the group.
• None—The host has no access to the group.
Permission
Indicates the LUN that the DPM uses to expose the mirrored virtual disk to a host. LUN
Sync mirror group information—Data Path Module/VSM tab
The Data Path Module/VSM tab provides information about the DPMs and VSM servers that service
the virtual disk, and identifies the primary and active servers.
Table 124 Sync mirror group Data Path Module/VSM tab fields
Description Property
The name of a DPM or VSM server that services the sync mirror group. Data Path Module
The status of the DPM. Possible values are:
• Present—The DPM is recognized and communicating correctly with the active
VSM server. The fabric agents on DPMs are pooling to the active VSM server
through all HBAs as expected.
• Degraded—The VSM fabric agent running on the DPM is no longer pooling
to the active VSM server through all back-end HBAs. There is at least one back-
end HBA through which the VSM server and the DPM are communicating
correctly.
• Absent—The DPM is not detected on the SAN
• Failed—The DPM is recognized on the SAN but is not communicating with the
active VSM server. The agent running on the DPM stopped polling to the active
VSM.
