Job Planning - Tru64 UNIX Suspending I/O before replicating AdvFS volumes - Tru64 UNIX If you plan to replicate an AdvFS host volume or volume group (fileset or domain) that has heavy I/O, HP recommends that the job include steps to briefly suspend I/O of the appropriate mount points just before the replication steps. When generating a job template, select the option Suspend Source Before Replication to add the steps. If creating a custom job, manually enter the steps. Below is an example. Line Task ... 14 // Suspend the host application. 15 Launch ( $source_host, %suspend_command_line%, "", WAIT, "0" ) onerror pauseat E1: 16 DO { 17 $Rep1 = SnapshotHostVolume ( $source_hostvol_unc1, FULLY_ALLOCATED, SAME, NOWAIT ) onerror pauseat E1: 18 // 19 } ALWAYS { 20 // Resume the host application. 21 Launch ( $source_host, %resume_command_line%, "", WAIT, "0" ) 22 } 23 // ... In the first Launch command (example, line 15) enter a host command or script file name to suspend I/O (freeze the mount point). For example, the syntax for the freezefs utility is: "freezefs -t -1 /mountPoint" Be sure to include the -1 argument. This prevents the OS from automatically performing a subsequent thaw. If omitted, the job can fail on the resume step (example, line 21). 162 Jobs
