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 ( fi leset or domain) that has heavy I/O,
HP recommends that the job include steps to brie fl y 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 fi rst Launch command (example, line 15) enter a host command or script fi le 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).
