Cluster Quorum Device Operations Operation Display quorum information Remove a quorum device Add a quorum device Command scstat scconf scconf Example scstat -q scconf -r -q globaldev=d30 scconf -a -q globaldev=d12 Put into maintenance state Bring out of maintenance state
scconf scconf
scconf -c -q globaldev=d15,maintstate scconf -c -q globaldev=d15,reset
Veritas Volume Manager Operations Operation Add disk group to cluster Register change to disk group Switch device group to a node Check status Change properties Command scconf scconf scswitch scstat scconf Example scconf -a -D type=vxvm,name=m-dg,nodelist=nodeA:nodeB scconf -c -D name=mydg,sync scswitch -z -D mydg -h nodeA (node to switch to) scstat -D scconf -c -D name=mydg,nodelist=nodeA:nodeB, preferenced=true,failback=disabled Nafo Group Operations Operation Creating nafo group Deleting nafo group Adding a card Removing card Switching active adaptor Check status Display current configuration Which group a card belongs to Which is the active card Change pnm parameters Command pnmset pnmset pnmset pnmset pnmset pnmset pnmset pnmrtop pnmptor vi Example pnmset -c nafo0 -o create hme0 qfe0 pnmset -c nafo0 -o delete pnmset -c nafo0 -o add qfe0 pnmset -c nafo0 -o remove qfe0 pnmset -c nafo0 -o switch qfe0 (Adaptor to switch to) pnmset -l pnmset -p pnmrtop hme0 pnmptor nafo0 vi /etc/cluster/pnmparams Resource Group Operations Operation Check current status View configuration Switch to a node Take offline on all nodes Bring online on primary node Brine online on named node Put into unmanaged state Bring into managed state Restart resource group Disable resource Enable resource Clear STOP_FAILED flag
Command scstat scrgadm scswitch scswitch scswitch scswitch scswitch scswitch scswitch scswitch scswitch scswitch
Example scstat -g scrgadm -p [-pvv] -g my-rg scswitch -z -g my-rg -h nodeB (Bring online on nodeB) scswitch -F -g my-rg scswitch -Z -g my-rg scswitch -z -g my-rg -h nodeB scswitch -F -g my-rg scswitch -n -j my-res (Disable all resource in group) scswitch -u -g my-rg scswitch -Z my-rg scswitch -R -h nodeB -g my-rg scswitch -n -j my-resource scswitch -e -j my-resource scswitch -c -h nodeB -j my-resource -f STOP_FAILED
Device Group Operations Operation Check current status Switch to a node Put into maintenance Bring online
Command scstat scswitch scswitch scswitch
Example scstat -D scswitch -z -D my-dg -h nodeA scswitch -m -D my-dg scswitch -z -D my-dg -h nodeB
Resource Group Configuration Operation Create Resource Group Command Example scrgadm -a -g my-rg -h nodeA,nodeB [ -y Pathprefix=/my-directory ] Add resource to Group scrgadm -a -j my-res -g my-rg -t SUNW.nfs -x ServicePaths=/my-directory 1. scswitch -F -g my-rg (Switch resource group offline) 2. scswitch -n -j my-res (Disable resource) 3. scrgadm -r -j my-res (Remove resource) 4. scswitch -Z my-rg (bring resource group on-line) scrgadm -a -L -j my-lh -g my-rg -l logical_host_name scrgadm -a -S -j my_salh -g my-rg -l logical_host_name scrgadm -a -j my-res -x property=new_value 1. scstat -g (List group and its resources) 2. scswitch -F -g my-rg (Switch resource group offline) Remove resource from group Add logical host resource Add share address resource Modify resource parameter Remove a resource group 3. scswitch -n -j my-res (Disable resources) 4. scrgadm -r -j my-res (Remove resources) 5. scrgadm -r -g my-rg (Remove resource group)
