Corrective actionProblem
• Verify that all VSM HBAs are properly zoned to
the EVA or MSA. If the VSM or DPM can see any
LUN from the EVA or MSA with the correct number
of paths, then the problem is not zoning.
• Verify that all DPM back-side ports are properly
zoned to the EVA or MSA.
• Verify that all VSM HBAs are properly defined in
HP Command View EVA or the ACU with one host
name for each VSM associated with all HBAs in-
stalled in that VSM.
• Verify that all DPM back-side ports are properly
defined in HP Command View EVA or the ACU
with at least one host name for each DPM associ-
ated with all back-side ports in that DPM. Also
supported is one EVA or MSA host name per DPM
“quad.”
• Compare the VSM listing of virtual disks with the
DPM Path Info table in the sac.log. Verify that
the DPM sees all of the paths to the virtual disks.
• Verify that all EVA or MSA virtual disks are
presented to both VSMs and both DPMs.
VSM/DPM does not see any virtual disks on the EVA
or MSA
Verify that each of the server's HBAs are zoned to one
front-side port per DPM.
VSM does not see the HBA of a new server.
A degraded status means that one of the server's HBAs
is not visible on the SAN.
• Verify all of the server’s HBAs indicate a link to the
SAN.
• Verify the HBA is zoned to one port of each DPM.
VSM lists the status of a server as degraded.
