Maintenance CommandsNAMESYNOPSISnsrd ( 1m )nsrd – daemon providing the NetWorker servicensrd [ – k virtual-service-name ]ansrd [ commentary ]DESCRIPTIONThe nsrd daemon provides an RPC-based save and recover service. This service allowsusers to save, query for, and recover their files across a network. The RPC programnumber provided by nsrd is 390103.Normally nsrd is invoked from a startup shell script (for example rc.local, rc.boot) atboot-time, and should never need to be started directly by a user. After it is started,nsrd starts up the other daemons it needs to provide the NetWorker service.The nsrd command must be run on a machine with appropriate resources. Requiredresources include both devices, such as tape drives, and sufficient disk space for theindex daemons, (see nsrindexd(1m) and nsrmmdbd(1m)). The devices are controlledby multiplexor software (see nsrmmd(1m)), and the disk space is used to maintain theindex of saved user files and volumes with corresponding files.Each time a backup, recover, or another session begins, nsrd starts the program, ansrd,to process the requested session. The ansrd program is called an agent. The agent isin charge of monitoring that backup, recover, or another session, and automaticallyexits when a session completes. Using ps(1) or another process monitoring tool, youcan inspect the subsequent parameters of ansrd to see what kind of session it is monitoring. If necessary, agents can be forcibly terminated to abort a backup or recoversession. Agents cannot be run directly; they can only be started by nsrd.When nsrd is started with the – k option, it checks to see whether it has been installedas a cluster service and that the virtual host which owns /nsr/res matches virtualservice-name. If either of these validation steps fails, nsrd exits immediately. (To checkwhether NetWorker has been installed as a cluster service, nsrd checks for a file calledNetWorker.clustersvr in the directory containing the nsrd binary. To check that/nsr/res is owned by virtual-service-name, nsrd queries the cluster managementsoftware.)If the – k option is not used when starting NetWorker in a cluster, the server assumesthe identity of the virtual host which owns /nsr/res. If no virtual host owns /nsr/res,then nsrd will not start.OPTIONSFILES– k virtual-service-nameInstructs nsrd to start up in cluster failover mode using virtual-service-name asits hostname/identity. This option is used by the NetWorker cluster controlscript which starts NetWorker./nsr/logs/daemon.rawThe file to which nsrd and other NetWorker daemons send informationabout various error conditions that cannot otherwise be logged using theNetWorker event mechanism./nsr/res/nsrdbInformation describing the NetWorker service and its resources (Seensr service(5)).NetWorker.clustersvrIf this file exists in the directory containing NetWorker’s daemons, it indicates that the NetWorker server has been installed as a cluster service.NetWorker 8.15

Maintenance CommandsNAMESYNOPSISDESCRIPTIONOPTIONSascdcode ( 1m )ascdcode – print error message for ASC/ASCQ error codesascdcode [ -o vendor id [ – p product id ] ] ASC ASCQThe ascdcode program interprets Additional Sense Code (ASC) and Additional SenseCode Qualifier (ASCQ) data and returns an appropriate error message. The ascdcodeprogram returns interpreted ASC/ASCQ data either for the named vendor and product IDs (with the -o and -p options), or for all libraries or devices as defined in theSCSI-3 Specifications (http://www.ncits.org) or individual vendors. For unimplemented ASC/ASCQ codes, the ascdcode program will return the message Not implemented.– o vendor idChecks to see if the vendor is an OEM and looks up the ASC/ASCQ errorcodes defined original vendor for the library or device. If the – p option is notspecified, ascdcode will return vendor specific information for the vendor idspecified with this option. The vendor id should be identical to the vendorstring reported when you run the inquire program. For a complete list of vendor ID assignments, see the web page: http://www.t10.org/lists/vid-alph.htm.This option is only applicable to vendor specific ASC/ASCQ codes of value(s)greater than 0x7f.– p product idUse with – o to provide a library or device type with the OEM vendor. Theproduct id should be identical to the library or device string reported when yourun the inquire program.The ASC argument should be the first of the pair of ASC/ASCQ error codesreported by the library or device. You may specify the value as a hexadecimalnumber by preceding the value with 0x . The default value is assumed to be adecimal value.The ASCQ argument should be the latter of the pair of ASC/ASCQ error codesreported by the library or device. You may specify the value as a hexadecimalnumber by preceding the value with 0x . The default value is assumed to be adecimal value.FILES/INSTALL PATH/lgtovendorsThe directory where the vendor specific files are installed./INSTALL PATH/lgtovendors/OEM MAPThe file that maps OEM vendors and their corresponding products to original vendors. See the file for a description on how to add entries for newOEM vendors and products.SEE ALSOLIMITATIONSlibscsi(1m)The ascdcode program always uses the installed vendor specific files to look up vendor specific error messages. Formatting convention of ASC/ASCQ error codes andtheir corresponding error text in these files are of the form:0x[ASC], 0x[ASCQ], [error message]NetWorker 8.17
