Function New-AGMLibMultiMount ([string]$csvfile,[array]$imagelist,[array]$hostlist,[string]$hostid,[string]$mountpoint,[switch][alias("a")]$appnamesuffix, [switch][alias("h")]$hostnamesuffix,[switch][alias("c")]$condatesuffix,[switch][alias("i")]$imagesuffix,[string]$label,[int]$startindex) { <# .SYNOPSIS Mounts a number of FileSystems to a group of hosts .EXAMPLE New-AGMLibMultiMount -imagelist $imagelist -hostlist $hostlist -mountpoint /tmp/imagecheck This command likes to use the output of Get-AGMLibImageRange as $imagelist So we could create a list like this: $imagelist = Get-AGMLibImageRange -fuzzyappname demo-sql -olderlimit 3 We could get a list of hosts to mount to with a command like this: $hostlist = Get-AGMHost -filtervalue "hostname~scanhost*" | select id,hostname The logic to handle mount points is simple. The user must supply a starter mount point with a trailing slash. For linux hosts this would be: -mountpoint /tmp/testmount/ For Windows hosts this would be: -mountpoint C:\temp\ The suffix is optional but recommended. This basically adds an extra foldername to the mount point. There are four mechanisms to get unique mount names: 1) You can specify -h and the Host Name will be used as part of the mount point 2) You can specify -a and the App Name will be used as part of the mount point 3) You can specify -i and the Image Name will be used as part of the mount point 4) You can specify -c and the Consistency Date will be used as part of the mountpoint The point point will always end in a unique number to guarantee uniqueness. If you want to control the starting number of that number use -startindex By default it will use a label of "MultiFS Recovery" to make the mounts easier to find. you can changes this with -label xxxx to set your own unique label. .EXAMPLE New-AGMLibMultiMount -imagelist $imagelist -hostid $hostid -mountpoint "/tmp/testmount/" If you only have a single host you can specify it singly using -hostid All your mounts will go to that single Host #> if ( (!($AGMSESSIONID)) -or (!($AGMIP)) ) { Get-AGMErrorMessage -messagetoprint "Not logged in or session expired.
