Server Cannot Be Located
If the matrix reports that it cannot locate a server on the SAN but you
know that the server is connected, there may be an FC switch problem.
On a Brocade FC switch, log into the switch and verify that all F-Port and
L-Port IDs specified in switchshow also appear in the local nameserver,
nsshow. If the lists of ports are different, reboot the switch. If the reboot
does not clear the problem, there may be a problem with the switch.
Also consult your FC switch documentation or the FC switch vendor. If
the switch appears to be operating properly, contact PolyServe Technical
Support.
Online Insertion of New Storage
Matrix Server supports online insertion (OLI) of new storage, provided
that OLI support is present for your combination of storage device, SAN
fabric, HBA vendor-supplied device driver, and the associated HBA
vendor-supplied libhbaapi. (Check with your vendors to determine
whether OLI is supported.)
NOTE: OLI of new storage can cause an interruption of normal
operations on your storage device. Because of this, it is
recommended that OLI of new storage be scheduled for off-peak
hours.
When the appropriate lower-level OLI support is in place, inserting a new
disk will cause a new device to automatically become eligible for
importing. The disk can be imported with the Management Console or
mx utility, and can be used normally from that point forward.
If OLI is not possible with your hardware combination, you will need to
reboot the servers after inserting a new disk. The disk will then be visible
to the matrix.
