It's not clear what applications are running on this server, but if a HDD or controller fault is suspected, you may install smart monitor tools to check for hardware related issues.

I have some questions regarding disk perfomance, and what I can do to make it just a little (or much :)) more faster.
From what I've heard the first partitions will be faster than the later ones because tracks at the outer edges of a hard drive platter simply moves faster. But I've also read in... (4 Replies)

About 4 years ago I wrote this tool inspired by Rob Urban's collect tool for DEC's Tru64 Unix. What makes this tool as different as collect was in its day is its ability to run at a low overhead and collect tons of stuff. I've expanded the general concept and even include data not available in... (0 Replies)

NAME
smartcard - overview of smart card features on Solaris
DESCRIPTION
The smart card framework provides a mechanism to abstract the details of interacting with smart cards and smart cardreaders (called card
terminals). The framework is based on the OpenCard Framework V1.1 (OCF) with Sun extensions to allow OCF to operate in a multi-user envi-
ronment. The core OCF software protocol stack is implemented as a system service daemon. This implementation allows smart cards and card
terminals to be shared cooperatively among many different clients on the system while providing access control to the smart card and card
terminal resources on a per-UID basis.
An event dispatcher is provided to inform clients of events occuring on the card and at the card terminal, such as card insertion and card
removal.
A high-level authentication mechanism is provided to allow clients to perform smart card-based authentications without requiring knowledge
of specific card or reader authentication features.
A set of applet administration tools is provided for JavaCards that support downloading Java applets (although applet build tools are not
provided).
Administration of the smart card framework is provided with the smartcard(1M) command line administration utility and the smartcardguiad-
min(1) GUI administration tool.
Support the following card terminal is provided:
o Dallas iButton Serial Reader (see ocf_ibutton(7D))
Additional card terminals can be supported by implementing smart card terminal interfaces in a shared library.
Support for several smart cards is provided:
o Schlumberger Cyberflex Access JavaCard
o Schlumberger MicroPayflex
o Dallas Semiconductor Java iButton JavaCard
Each of the supported cards has a complete set of OCF card services that implement the necessary functionality for authentication and
secure storage of data. For the two supported JavaCards, an authentication and secure data storage applet is provided that can be loaded
into these cards with the supplied applet administration tools. See smartcard(1M).
A PAM smart card module is provided to allow PAM clients to use smart card-based authentication. See pam_smartcard(5)
CDE is able to use the PAM smart card module for dtlogin and dtsession authentication. CDE also uses the smart card framework event dis-
patcher to listen for events on the card terminal and provide corresponding visual feedback to the user.
