Slices (Partitions)

With Sun Solaris, each file system is assigned to a slice (group of cylinders). Each slice appears to the operating system as a separate disk drive. In some displays, for example the format utility, slices are referred to as partitions.

 

Specifying a Slice Number

To mount a BCV unit as part of an EVM job, you must specify its slice number when you create the job. The slice number of the BCV unit must be the same as the slice number of the source unit.

If you are a superuser, you can identify the slice number of a disk using the format utility. Typical slice numbers and uses are listed below.

Solaris (SPARC) Typical Slices

Slice File system Use

0

root Operating system directories and files

1

swap Virtual memory (swap space )

2

- Refers to the entire disk

3

/export Alternative versions of the operating system. For example, a version required by a client system with a different architecture than the server.

4

/export/swap Virtual memory (swap space) for client systems

5

/opt Application software. (The /opt directory is sometimes mounted in slice 0.)

6

/usr Programs (executables) designed to be run by users. Also documentation, system programs (e.g. init and syslogd) and library routines.

7

/home or
/export home
User files

 

Excluding StorageWorks Partitioned Units from EVM Jobs

You cannot use an EVM job to replicate storage units that have been partitioned using StorageWorks.
