Maintaining Storage Arrays
This section contains the procedures about how to maintain a storage array in a
running cluster.
Table 1–3 lists these procedures.
Note –
When you upgrade firmware on a storage device or on an enclosure, redefine
the stripe size of a LUN, or perform other LUN operations, a device ID might change
unexpectedly. When you perform a check of the device ID configuration by running
the
scdidadm -c
command, the following error message appears on your console if
the device ID changed unexpectedly.
