This advisor to solar management is areference handbook written via solar directors for solar directors. The ebook isn't in­ tended to be an entire advisor to UNIX structures management; in its place it is going to pay attention to the unique matters which are specific to the solar setting. it's going to take you thru the elemental steps essential to set up and continue a community of solar pcs. alongside the way in which, valuable rules might be given relating NFS, YP, backup and fix tactics, in addition to many helpful install suggestions that could make a approach administrator's task much less painful. Spe­ cifically, SunGS 4.0 via 4.0.3 could be studied; despite the fact that, many ofthe principles and ideas offered are known adequate for use on any model of SunGS. This ebook isn't really meant to be simple advent to SunGS. it really is assumed thatthe reader can have at the least a yr ofexperience helping UNIX. BookOverview The firstchaptergives adescription ofthe method forms thatwill be mentioned through the e-book. An figuring out of all the procedure forms is required to understand the remaining ofthe booklet. bankruptcy 2 presents the data essential to set up a laptop. The layout software and the stairs taken with the suninstall approach are coated intimately. rules and ideas approximately partitioning are integrated during this bankruptcy. YP is the subject of the 3rd bankruptcy. a selected description of every YPmap and every YPcommand ispresented, in addition to a few pointers on how you can top make the most of this package deal on your environment.

Example text

The contents of /export in this situation do not change very often because diskless clients mount the /usr files with a read-only option. Frequent tape backups of this partition are not necessary. The /export/root directory contains the root files for each diskless client served. There are many files under root, such as /var/ spool/mail/ that may be lost forever if not archived before a disk crash. The filesystem containing the client's root files needs to be backed-up daily. Configuring all the root files in one partition makes them easier to backup, while leaving the more constant directories alone.

The root and swap resources for each cli ent are not shared. The application or major architecture nam e is used as a path to lexport/exec/ because they are binary compatible. Sun-4 and Sun-4c clients share the lexport/exec/sun4 directory while Sun-3 and Sun-3x clients share lexport/ex ec /sun3 . Also resident under th e lexport/exec directory is the subdirectory call ed kvm. The le xport/exe c/ kvm directory contains kernel specific file s pertaining to each archite cture served. This is where kernel and applicati on architectures differ.

It can then boot over the network so that you can run the format program. See Chapter 4 for detailed instructions on how to set up and boot diskless clients. There are other special requirements when a diskless system is being used to run format. The UNIX kernel used by some diskless machines does not contain the drivers necessary for disk devices . Be sure to use the GENERIC kernel for that architecture when booting to cover all possibilities. Copy a GENERIC kernel into the client's Iexport/rootl directory before booting.
