For devices that are opened and closed frequently (such as tapes), data might not be reported for the

activity in the prior interval. The data might not be reported, because the device might be closed at the

instant when data is collected. The recommendation for such devices is to use shorter intervals (t )of

seconds.

When multi-pathing is enabled and I/O is issued on a legacy LUN,

sar -d

may not report I/O that is

redirected through other paths to the agile device.

The behavior of the

sa1 and sa2 scripts and the

sadc command remain unaltered with the SAR-

MEMFS product; these scripts and command do not record data reported by the

-z option.
