====== A collection of PS commands for TSM / ISP ======
===== getting Hardware information =====
  * get WWN of installed FC-HBA <code>Get-WmiObject -class MSFC_FCAdapterHBAAttributes -namespace “root\WMI” | ForEach-Object {(($_.NodeWWN) | ForEach-Object {“{0:x}” -f $_}) -join “:”}</code>e.g.:{{ :en:services:storage_services:backup:admin:ps-get-wwn.png |}}

===== 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.
