NS0-155 Exam Dumps : Data ONTAP 7-Mode Administrator

The rules for the selection of disks or array LUNs, for using as mirrored aggregates, are as follows:

Disks or array LUNs selected for each plex must be in different pools.

The same number of disks or array LUNs must be in both the plexes.

Disks are selected first on the basis of equivalent bytes per sector (bps) size, then on the basis of the size of the disk.

If there is no equivalent-sized disk, Data ONTAP uses a larger-capacity disk, and limits the size to make it identically sized.

Data ONTAP names the plexes of the mirrored aggregate.

The pktt command controls a simple on-filer packet tracing facility. Packets can be captured into a trace buffer then dumped to a file, or the captured data can be logged to a file. The data is stored in "tcpdump" format, and can be directly viewed with tcpdump, ethereal, and perhaps other viewers. The output can also be converted using the editcap(1) program to a variety of other formats, including Sniffer, NetMon, and snoop.

The operator must ensure that the partner filer does not become operational at any time while a filer is in a takeover mode initiated by the use of this command
