Solaris 10 What's New

System Administration Enhancements

The following system administration features and enhancements have been added to the Solaris 10 10/09 release.

Two-Terabyte Disk Support for Installing and Booting the Solaris OS

Starting with the Solaris 10 10/09 release, you can install and boot the Solaris OS from a disk that is up to 2 Tbytes in size. In previous Solaris releases, you could not install and boot the Solaris OS from a disk that was greater than 1 Tbyte in size.

In this Solaris release, you can use the VTOC label on a disk of any size. However, the addressable space by the VTOC is limited to 2 Tbytes. This feature enables disks that are larger than 2 Tbytes to also be used as boot drive. However, the usable space from label is limited to 2 Tbytes.

This feature is available only on systems that run a 64-bit kernel. A minimum of 1 Gbyte of memory is required for x86–based systems.

For more information about the Solaris disk drivers and disk utilities that have been updated to support boot on disks greater than 1 Tbyte, see System Administration Guide: Devices and File Systems.

pcitool Utility

The pcitool utility enables system administrators to bind interrupts to specific hardware strands for enhanced performance. This utility exists in the public SUNWio-tools package. For more information about using pcitool, see the pcitool man page.

ZFS Features and Changes

The following section summarizes new features in the ZFS file system.

For more information about these improvements and changes, see the Solaris ZFS Administration Guide.

See the following What's New sections for related ZFS feature information:

nss_ldap shadowAccount Support

The LDAP name service is enhanced to support the account locking and password aging functionality using the data in the shadow database stored on a configured LDAP server. This support enables the passwd(1) utility and the pam_unix_*(5) PAM modules to function almost the same when handling account locking and password aging for local accounts and remote LDAP user accounts. Therefore, using the pam_ldap(5) module is no longer the only way to implement the password policy and account control for the LDAP name service. pam_unix_*(5) can be used to obtain the same consistent results as with the files and nisplus name services.

For more information, see System Administration Guide: Naming and Directory Services (DNS, NIS, and LDAP).
