snapmirror resume destination

Resumes transfers to destination. The snapmirror resume command can be used either to abort a

snapmirror quiesce in progress or undo a previously completed snapmirror quiesce. The command restores the state of the destination from quiescing or quiesced to whatever it was prior to the quiesce operation.

aggr destroy { aggrname | plexname } [ -f ]

Destroys the aggregate named aggrname, or the plex named plexname. Note that if the specified aggregate is tied to a traditional volume, then the traditional volume itself is destroyed as well.

If an aggregate is specified, all plexes in the aggregate are destroyed. The named aggregate must also not contain any flexible volumes, regardless of their mount state (online, restricted, or offline). If a plex is specified, the plex is destroyed, leaving an unmirrored aggregate or traditional volume containing the remaining plex.

Before destroying the aggregate, traditional volume or plex, the user is prompted to confirm the operation. The -f flag can be used to destroy an aggregate, traditional volume or plex without prompting the user.

The disks originally in the destroyed object become spare disks. Only offline aggregates, traditional volumes and plexes can be destroyed.

Separating the disk and tape devices into separate zones prevents disk RSCNs from impacting tape devices, which tend to be more sensitive to RSCNs.

Best practice is to zone each initiator WWPN to each target WWPN individually.

disk show [ -o < ownername > | -s < sysid > | -n | -v | -a]

Used to display information about the ownership of the disks. Available only on systems with software-based disk ownership. -o lists all disks owned by the filer with the name < ownername > -s lists all disks owned by the filer with the serial number < sysid > -n lists all unassigned disks. -v lists all disks. -a lists all assigned disks.

quota resize volume

Adjusts currently active quotas in the specified volume to reflect changes in the /etc/quotas file. For instance, if you edit an entry in /etc/quotas to increase a user ' s quota, quota resize will cause the change to take effect. The volume name may be omitted if the system has only one volume. quota resize can be used only when quotas are already on. Because it does not rescan the file system to compute usage, quota resize is faster than turning quotas off and then on again. quota resize will apply all updated entries in /etc/quotas; however, it will generally ignore newly added entries. A newly added entry will only take effect if the corresponding user or group has an active quota as a result of updating a file subject to default quotas.

The snaplock command manages compliance related functionality on the system. A volume created using the vol command (see na_vol(1)) is a snaplock volume when either the enterprise or compliance option is chosen.

Enterprise and compliance SnapLock volumes allow different levels of security assurance.

SnapLock operates fundamentally at the file level.

igroup show [ -v ] [ initiator_group ] Displays the nodes in an initiator group and their aliases, set with the fcp wwpnalias command. If no initiator_group is specified, the members of all initiator groups are displayed. You can use the -v option to get a verbose listing.

lun show [ -v | -m | -c ] [ all | mapped | offline | online | unmapped | staging |

-g initiator_group | -n node | -l vol_name | lun_path ] Displays the status (lun_path, size, online/offline state, shared state) of the given LUN or class of LUNs. With the -v option supplied, additional information (comment string, serial number, LUN mapping, HA Pair Shared Volume Information) is also displayed. With the -m option supplied, information about lun_path to initiator_group mappings is displayed in a table format. With the -c option supplied, information about LUN cloning status is displayed.

lun set reservation lun_path [ enable | disable ]

Enables or disables the space reservation on the LUN. If no arguments are supplied after the lun_path, then the space reservation status of the given lun_path is displayed.

lun create -s size -t ostype [ -o noreserve ] [ -e space_alloc ] lun_path

This usage of the lun create command should be employed to create a new LUN of given size, with initially zero contents. The LUN is created at the lun_path given. No file should already exist at the given lun_path. The directory specified in the lun_path must be a qtree root directory.

The size is specified in bytes. Optionally, a number followed by a one-character multiplier suffix can be used: c (1), w (2), b (512), k (1024), m (k*k), g (k*m), t (m*m).

The size of the created LUN could be larger than the size specified, in order to get an integral number of cylinders while reporting the geometry using SAN protocols.

The size of the LUN actually created is reported if it is different from that specified in the command.

The mandatory ostype argument is one of: solaris (the LUN will be used to store a Solaris raw disk in a singleslice partition), windows (the LUN will be used to store a raw disk device in a single-partition Windows disk using the MBR (Master Boot Record) partitioning style), hpux (the LUN will be used to store HP-UX data), aix (the LUN will be used to store AIX data), vld (the LUN contains a SnapManager VLD), linux (the LUN will be used to store a Linux raw disk without any partition table), netware (the LUN will be used to store NetWare data), vmware (the LUN will be used to store VMware data), windows_gpt (the LUN will be used to store Windows data using the GPT (GUID Partition Type) partitioning style), windows_2008 (the LUN will be used to store Windows data for Windows 2008 systems), openvms (the LUN will be used to store Open-VMS data), xen (the LUN will be used to store Xen data), hyper_v (the LUN will be used to store Hyper-V data), solaris_efi

By default, the LUN is space-reserved. To manage space usage manually, -o noreserve can be specified.

Using this option will create a LUN without any space being reserved. Provisioning threshold events can be enabled by specifying -e space_alloc option. This option has to be used in conjunction with -o noreserve.

lun map [ -f ] lun_path initiator_group [ lun_id ]

Maps a LUN to all the initiators in the supplied group. If a LUN ID is not specified, the smallest number that can be used for the various initiators in the group is automatically picked. Note that this command can be used multiple times to configure multiple maps for a LUN, or for an initiator group. Once created, you can use lun show -m to list all the LUN mappings.

The optional -f argument disables checking with the HA partner for LUN mapping conflicts.

pktt is part of the Data OnTap command set.

The output of pktt is not very human-readable, but it utilizes the tcpdump format which many traffic analyzers can read or import. Only two such analyzers have been offered here.

Wireshark is the successor of Etherreal, and available for several platforms. Netmon is a Microsoft project, available for Windows, soon to be deprecated by the Microsoft Message Analyzer project.
