178 Advanced topics related to installing VCSReconciling major/minor numbers for NFS shared disksChecking major and minor numbers for disk partitionsThe following sections describe checking and changing, if necessary, the majorand minor numbers for disk partitions used by cluster nodes.To check major and minor numbers on disk partitions◆Use the following command on all nodes exporting an NFS file system. Thiscommand displays the major and minor numbers for the block device.# ls -lL block_deviceThe variable block_device refers to a partition on which a file system ismounted for export via NFS. Use this command on each NFS file system. Forexample, type:# ls -lL /dev/dsk/c1t1d0s3Output on Node A resembles:crw-r----- 1 root sys 32,1 Dec 3 11:50 /dev/dsk/c1t1d0s3Output on Node B resembles:crw-r----- 1 root sys 32,1 Dec 3 11:55 /dev/dsk/c1t1d0s3Note that the major numbers (32) and the minor numbers (1) match,satisfactorily meeting the requirement for NFS file systems.To reconcile major numbers that do not match on disk partitions1 Reconcile the major and minor numbers, if required. For example, if theoutput in the previous section resembles the following, perform theinstructions beginning step 2:Output on Node A:crw-r----- 1 root sys 32,1 Dec 3 11:50 /dev/dsk/c1t1d0s3Output on Node B:crw-r-----1 root sys 36,1 Dec 3 11:55 /dev/dsk/c1t1d0s32 Place the VCS command directory in your path. For example:# export PATH=$PATH:/usr/sbin:/sbin:/opt/VRTS/bin3 Attempt to change the major number on System B (now 36) to match that ofSystem A (32). Use the command:# haremajor -sd major_numberFor example, on Node B, enter:# haremajor -sd 324 If the command succeeds, go to step 8.5 If the command fails, you may see a message resembling:Error: Preexisiting major number 32These are available numbers on this system: 128...Check /etc/name_to_major on all systems foravailable numbers.
Advanced topics related to installing VCSReconciling major/minor numbers for NFS shared disks1796 Notice that the number 36 (the major number on Node A) is not available onNode B. Run the haremajor command on Node B and change it to 128,# haremajor -sd 1287 Run the same command on Node A. If the command fails on Node A, theoutput lists the available numbers. Rerun the command on both nodes,setting the major number to one available to both.8 Reboot each system on which the command succeeds.9 Proceed to reconcile the major numbers for your next partition.To reconcile minor numbers that do not match on disk partitions1 Complete the following steps. In the example, the minor numbers are 1 and3 and are reconciled by setting to 30 on each node.2 Type the following command on both nodes using the name of the blockdevice:# ls -1 /dev/dsk/c1t1d0s3Output from this command resembles the following on Node A:lrwxrwxrwx 1 root root 83 Dec 3 11:50 /dev/dsk/c1t1d0s3 -> ../../ devices/sbus@1f,0/QLGC,isp@0,10000/sd@1,0:d,rawThe device name (in bold) includes the slash following the word devices,and continues to, but does not include, the colon.3 Type the following command on both nodes to determine the instancenumbers used by the SCSI driver:# grep sd /etc/path_to_inst | sort -n -k 2,2Output from this command resembles the following on Node A:"/sbus@1f,0/QLGC,isp@0,10000/sd@0,0" 0 "sd""/sbus@1f,0/QLGC,isp@0,10000/sd@1,0" 1 "sd""/sbus@1f,0/QLGC,isp@0,10000/sd@2,0" 2 "sd""/sbus@1f,0/QLGC,isp@0,10000/sd@3,0" 3 "sd".."/sbus@1f,0/SUNW,fas@e,8800000/sd@d,0" 27 "sd""/sbus@1f,0/SUNW,fas@e,8800000/sd@e,0" 28 "sd""/sbus@1f,0/SUNW,fas@e,8800000/sd@f,0" 29 "sd"In the output, the instance numbers are in the second field. The instancenumber associated with the device name that matches the name for Node Adisplayed in step 2, is “1.”4 Compare instance numbers the device in the output on each node.■If the instance number from one node is not used on the other (that is,it does not appear in the output of step 3), edit /etc/path_to_instto make the second node’s instance number similar to that of the firstnode.
