TradeOffs When Using Mirrors
A RAID-1 mirror volume maintains identical copies of the data in RAID-0 volumes. Mirroring requires more disks. You need at least twice as much disk space as the amount of data to be mirrored. After configuring a mirror, you can use it as if it were a physical slice. With multiple copies of data available, data access time is reduced if the mirror read and write policies are properly configured. You then use read and write policies to distribute the access to the submirrors evenly across the...

Logical Volume
The Solaris Volume Manager software uses virtual disks called logical volumes to manage physical disks and their associated data. Historically, a logical volume is functionally identical to a physical slice. However, a logical volume can span multiple disk members. The Solaris Volume Manager software converts I O requests directed at a volume into I O requests to the underlying member disks. You can create the Solaris Volume Manager software volumes from slices disk partitions or from other...
Monitoring a syslog File in Real Time
You can monitor the designated syslog file, in the var adm directory, in real time using the command tail -f. The tail -f command holds the file open so that you can view messages being written to the file by the syslogd daemon. To view messages sent to the var adm messages file, perform the command
grep rpcbind etcservices
Some rpcbind services start only on demand. The port numbers are registered with the rpcbind process during boot. Figure 2-5 shows the steps involved in requesting an RPC port address. When a client application requests a service, the rpcbind process returns the port number of the service to the client machine. The client machine generates a new request using the port number that it just received for the requested service. inetd.conf spray 1 rpc.sprayd rpc.sprayd portnnnnn inetd.conf spray 1...

Starting RPC Services
RPC services are services developed using a set of utilities developed by Sun Microsystems, Inc. While RPC services are assigned a unique program number by the programmer when they are written, the RPC services are not typically assigned to well-known ports. Services that start by default at system boot time Services that do not start automatically at boot and must start on RPC services started at boot time with startup scripts run on available ports above 32768. The rpcbind process associates...
Finish Scripts
Finish scripts are Bourne scripts that JumpStart clients run after installing the Solaris OE but before they reboot. Finish scripts allow you to perform a variety of post-installation tasks on the JumpStart client, including Setting the power-management configuration Retrieving backed-up data from a server on the network Copying selected files from a JumpStart server to the client The following example finish script causes the JumpStart client to turn off automatic shutdown for power...
Recalculating an ACL Mask
You can globally control the effective permissions of a custom ACL entry by using the ACL mask. However, examples in this module show that the ACL mask sometimes does not allow you to set some of the requested permissions that are indicated in the list of ACL entries. Therefore, recalculate the ACL mask, and modify it to allow all the requested permissions in the list of ACL entries. After recalculating the ACL mask, the effective permission of each ACL entry allows the full set of requested...
Verifying AutoFS Entries in the etcmnttab File
The etc mnttab file is a file system that provides read-only access to the table of mounted file systems for the current host. Mounting a file system adds an entry to this table. Unmounting a file system removes the entry from this table. Each entry in the table is a line of fields separated by spaces in the form of special mount_point fstype options time where The name of the resource to be mounted The path name of the directory on which the file system is mounted The time at which the file...

Subnet Restrictions
JumpStart clients broadcast RARP requests when they attempt to boot from the network. Broadcast network traffic is normally not forwarded to networks other than the one where the broadcast traffic originated. This situation requires that a JumpStart boot server exist on the same subnet to which JumpStart clients are directly connected. The initial network requests for boot-related services are the only JumpStart client requests that are limited by these subnet restrictions. Identification...
The syslogd Daemon and the m4 Macro Processor
Figure 13-3 shows how the syslogd daemon, the m4 macro processor, and the etc syslog.conf file interact in conceptual phases to determine the correct message routing. These conceptual phases are described as 1. The syslogd daemon runs the m4 macro processor. 2. The m4 processor reads the etc syslog.conf file, processes any m4 statements in the input, and passes the output to the syslogd daemon. The syslogd daemon uses the configuration information output by the m4 processor to route messages to...
The securenets File
The var yp securenets file limits access to NIS services. If the var yp securenets file exists on an NIS server, the server only answers queries or supplies maps to hosts and networks whose IP addresses exist in the file. The server must be able to access itself. To access itself, the server can be a part of the subnet that is allowed to access the server, or you can add the following entry The following example describes a securenets file where The server is configured to access itself. A...

A response of no answer from sys41 indicates that you cannot contact host sys41. This implies a problem with host sys41, or a problem with the network. For the ping command to succeed, the following conditions must be satisfied The interface must be plumbed. The interface must be configured. The interface must be physically connected. The interface must have valid routes configured. Note - Configuration of routes is an advanced networking topic. Detailed network administration concepts are...
Introducing NIS Fundamentals
NIS facilitates the creation of server systems that act as central repositories for several of the administrative files found on UNIX systems. The benefits of NIS include Centralized administration of files Better scaling of file administration as networks grow Figure 16-2 shows that NIS is organized into named administrative domains. Conceptually, within each domain there is one NIS master server, zero or more slave servers, and one or more clients. Figure 16-2 shows that NIS is organized into...
Soft Partitions
As disks become larger, and disk arrays present larger logical devices to Solaris OEs, users must be able to subdivide disks or logical volumes into more than eight sections, often to create manageable file systems or partition sizes. Soft partitions provide a mechanism for dividing large storage spaces into smaller, more manageable, sizes. For example, large storage aggregations provide redundant storage of many gigabytes, but many scenarios would not require as much space. Soft partitions...

NFS Server
The NFS server contains file resources shared with other systems on the network. A computer acts as a server when it makes files and directories on its hard disk available to the other computers on the network. Hostl share export rdbms Figure 6-2 NFS Server Configuration Figure 6-2 shows how files and directories on an NFS server are made available to NFS clients. The NFS server is sharing the export rdbms directory over NFS.
