cmvxserviced(1m) cmvxserviced(1m) NAME
cmvxserviced - monitor VxVM and CVM volumes for a high availability package. SYNOPSIS
cmvxserviced [-h|-v] [-O log_file] [-D log_level] [-t poll_interval] volume_path... DESCRIPTION
cmvxserviced monitors VxVM and CVM volumes. It runs as a service within a package that depends on the monitored storage. When a monitored volume fails or becomes inaccessible (see Scope of Monitoring), the service will exit, causing the package to fail on the current node. The package's failover behavior depends on its configured settings. cmvxserviced periodically probes each volume named by volume_path, which must identify a block device file. Scope of Monitoring The VxVM Volume Monitor detects the following failures: o Failure of the last link to a storage device or set of devices critical to volume operation o Failure of a storage device or set of devices critical to volume operation o An unexpected detachment or disablement of a volume The VxVM Volume Monitor does not detect the following failures: o Failure of a redundant link to a storage device or set of devices if a functioning link remains o Failure of a mirrored plex within a volume (assuming at least one plex is functional) o Corruption of data on a volume which VxVM or CVM regards as enabled and active Options cmvxserviced supports the following options: -h Displays the usage, as listed above, and exits. -v Displays the monitor version and exits. NOTE Do not include the -h or -v parameters in your service command; this will result in immediate package failure at runtime. -O log_file Specifies a file for logging (log messages are printed to the console by default). -D log_level Specifies the log level. The level of detail logged is directly proportional to the numerical value of the log level. That is, a log level of 7 will provide the greatest amount of log information. The default log level is 0. -t poll_interval Specifies the interval between volume probes. You can specify a polling interval of as little as 1 (one second), but bear in mind that a short polling interval (less than 10 seconds) may impair system performance if you are monitoring a large number of volumes. HP recom- mends a polling interval of at least 10 seconds if 50 or more volumes are being monitored by a single service com- mand. The default polling interval is 60 seconds. EXAMPLES
/usr/sbin/cmvxserviced -O /pkg1/monlog.log -D 3 /dev/vx/dsk/cvm_dg0/lvol2 This command monitors a single volume, /dev/vx/dsk/cvm_dg0/lvol2, at log level 3, with a polling interval of 60 seconds, and prints all log messages to the file /pkg1/monlog.log. There should be a one to one relationship between monitoring services and log files. This provides a means to correlate log messages with the originating monitor. /usr/sbin/cmvxserviced /dev/vx/dsk/cvm_dg0/lvol1 dev/vx/dsk/cvm_dg0/lvol2 This command monitors two volumes at the default log level of 0, with a polling interval of 60 seconds, and prints all log messages to the console. /usr/sbin/cmvxserviced -t 10 /dev/vx/dsk/cvm_dg2/lvol3 This command monitors a single volume at log level 0, with a polling interval of 10 seconds, and prints all log messages to the console.

ledmon(8) Intel(R) Enclosure LED Monitor Service ledmon(8) NAME
ledmon - Intel(R) LED monitor service for storage enclosures. SYNOPSIS
ledmon [OPTIONS] DESCRIPTION
The ledmon application is a daemon process used to monitor a state of software RAID devices (md only) or a state of block devices. The state is visualizing on LEDs associated to each slot in an enclosure or a drive bay. There are two types of system: 2-LEDs system (Activity LED, Status LED) and 3-LEDs system (Activity LED, Locate LED, Fail LED). This application has the highest priority when accessing the LEDs. The ledmon application uses SGPIO and SES-2 protocol to control LEDs. The program implements IBPI patterns of SFF-8489 specification for SGPIO. Please note some enclosures do not stick close to SFF-8489 specification. It might happen that enclosure processor will accept IBPI pattern but it will blink LEDs not according to SFF-8489 specification or it has limited number of patterns supported. LED management (AHCI) and SAF-TE protocols are not supported. There's no method provided to specify which RAID volume should be monitored and which not. The ledmon application monitors all RAID devices and visualizes their state. The ledmon application has been verified to work with Intel(R) storage controllers (i.e. Intel(R) AHCI controller). The application might work with storage controllers of other vendors (especially SAS/SCSI controllers). However storage controllers of other vendors have not been tested. The ledmon application is part of Intel(R) Enclosure LED Utilities. Only single instance of the application is allowed. OPTIONS
-c or --config=path Sets a path to local configuration file. If this option is specified the global configuration file and user configuration file has no effect. -l or --log=path Sets a path to local log file. If this option is specified the global log file /var/log/ledmon.log is not used. -t or --interval=seconds Sets time interval between scans of sysfs. The value is given in seconds. The minimum is 5 seconds the maximum is not specified. --quiet or --error or --warning or --info or --debug or --all Verbose level - 'quiet' means no logging at all and 'all' means to log everything. The levels are given in order. If user specifies more then one verbose option the last option comes into effect. -h or --help Prints this text out and exits. -v or --version Displays version of ledmon and information about the license and exits. FILES
/var/log/ledmon.log Global log file, used by ledmon application. To force logging to user defined file use -l option switch. ~/.ledctl User configuration file, shared between ledmon and all ledctl application instances. /etc/ledcfg.conf Global configuration file, shared between ledmon and all ledctl application instances.

The ledmon application does not recognize PFA state (Predicted Failure Analysis), hence the PFA pattern from SFF-8489 specification is not visualized. SEE ALSO
