A collection of PS commands for TSM / ISP

getting Hardware information

  • get WWN of installed FC-HBA
    Get-WmiObject -class MSFC_FCAdapterHBAAttributes -namespace “root\WMI” | ForEach-Object {(($_.NodeWWN) | ForEach-Object {“{0:x}” -f $_}) -join “:”}

chaning credentials of windows services

Ordinarily the sc.exe command can be used to change the credentials of a windows service. unfortunately the powershell does not easily support the use of sc.exe with a pipeline after the Get-Service commandlet :-( … and the powershell itself has no commandlet that works like the sc.exe command :-(

so the solution is a combination of both: getting all services to be changed and put them into an array and then run a for loop on this array:

$id=<[DOMAIN\]USER>;
$pw=<Password for user $ID>;
$svs=(Get-Service | Where-Object {$_.DisplayName -like "TSM Client SCHEDULER*" } | %{$_.Name});
foreach ($sv in $svs)
{
  sc.exe config $sv obj= "$id" password= "$pw";
  Restart-Service -Name "$sv";
  echo $sv;
}

consider: the | %{$_.Name} at the end of the pipe is necessary to get just the name, but no tabular output.
