Oracle Solaris 11 System Administrator 1z0-820 Book

The ipmpstat command concisely displays information about the IPMP subsystem. It supports five different output modes, each of which provides a different view of the IPMP subsystem (address, group, interface, probe, and target), described below.

-i

Display IP interface information (“interface” output mode).

Interface Mode

Interface mode displays the state of all IP interfaces that are tracked by in.mpathd on the system. The following output field is one of the supported:

FLAGS

Assorted information about the IP interface:

i

(D) Unusable due to being INACTIVE.

s

Marked STANDBY.

m

(E) Nominated to send/receive IPv4 multicast for its IPMP group.

b

Nominated to send/receive IPv4 broadcast for its IPMP group.

M

Nominated to send/receive IPv6 multicast for its IPMP group.

d

Unusable due to being down.

h

Unusable due to being brought OFFLINE by in.mpathd because of a duplicate hardware address.

mount: mount-point /DS9 does not exist.

To solve the mount point error condition, check that the mount point exists on the client. Check the spelling of the mount point on the command line or in the /etc/vfstab file (B) on the client, or comment outthe entry and reboot the system.

Note: The /etc/vfstab file lists all the file systems to be automatically mounted at system boot time, with the exception of the /etc/mnttab and /var/run file systems.

E: showmount

This command displays all clients that have remotely mounted file systems that are shared from an NFS server, or only the file systems that are mounted by clients, or the shared file systems with the client access information. The command syntax is:

showmount [ -ade ] [ hostname ]

where -a prints a list of all the remote mounts (each entry includes the client name and the directory), -d prints a list of the directories that are remotely mounted by clients, -e prints a list of the files shared (or exported), and hostname selects the NFS server to gather the information from. If hostname is not specified the local host is queried.

F: * mountd Daemon

This daemon handles file-system mount requests from remote systems and provides access control. The mountd daemon checks /etc/dfs/sharetab to determine which file systems are available for remote mounting and which systems are allowed to do the remote mounting.

* Commands for Troubleshooting NFS Problems

These commands can be useful when troubleshooting NFS problems.

rpcinfo Command

This command generates information about the RPC service that is running on a system.
