Operational considerations for saving storage

 

Before you save storage, take the information in this topic into consideration.

• You can only run the save storage process when the system is in a restricted state.

• The user must have save system (*SAVSYS) special authority to use the Save Storage (SAVSTG) command.

• The SAVSTG command causes the system to power down and starts the system again as though you specified PWRDWNSYS RESTART(*YES). An initial program load (IPL) of the system occurs after the command completes. The save storage function implicitly occurs during the IPL of the system from the dedicated service tools (DST) function.
  Attention logical partitioning users:

  • If you are going to use this command on the primary partition, be sure to power off all secondary partitions before running the command.

  • In order to save your entire system configuration, save each logical partition individually.

• You can save the first tape without an operator being present. After you save the first tape, DST messages appear that ask for the next tape so the save operation can continue.

• As the amount of storage on the system increases, the chance of an irrecoverable media error increases. Clean the tape unit frequently.

• You must specify a device name on the command. Expiration date (EXPDATE) and clear (CLEAR) parameters are optional. You cannot specify a volume ID.

• The save storage process does not start unless the console is available. If the console is not available, a system reference code appears on the control panel.

• When the save storage operation completes successfully, a normal IPL occurs.
