RVDSRV(8) —

NAME

rvdsrv − Remote Virtual Disk (RVD) server daemon

SYNOPSIS

/usr/ibm/rvdsrv [ −l loglevel ] [ −r [restart_file] ]

DESCRIPTION

Rvdsrv is the RVD server program which handles the physical media and services read and write requests from network connections. It also accepts control requests on a UDP port to perform other activities such as spin up or down a disk, create a virtual disk, or add a physical device. It logs actions into the syslog (see syslogd(8)).

Loglevel is compared against the following log levels:

#define LOG_ERR1/∗ log all packet errors ∗/
#define LOG_SPINS2/∗ log all spinups/spindown ∗/
#define LOG_RDWR4/∗ log all read and write requests ∗/
#define LOG_CLIENT_ERROR8/∗ log all client errors ∗/
#define LOG_TRACE16/∗ log a full packet trace ∗/

If a bit in loglevel is on, the corresponding logging occurs. For example, if loglevel is 5, read and write requests will be logged, along with packet errors.

The -r switch will cause the server to restart if it encounters a fatal error. During a crash the server will do a core dump and read commands from the default or given restart_file before aborting.

DIAGNOSTICS

Diagnostics are handled by syslog(8).
