| fence level is that if the package is running and a link goes |
| down, an array goes down, or the remote data center goes |
| down, then write(1) calls in the package application will |
| fail, causing the package to fail. |
| NOTE: The Continuous Access Journal is used for |
| asynchronous data replication. Fence level ascyn is used |
| for a journal group pair. |
| If the package is configured for three data centers (3DC), |
| this parameter holds the fence level of device group between |
| DC1 and DC2. As the device group between DC1 and DC2 |
| is always synchronous, the fence level either “data” or |
| “never”. The fence level of device group between DC2 and |
| DC3 or DC1 and DC3 is always assumed to be “async” |
| and user need not mention it. |
HORCMINST | This is the instance of the Raid Manager that the control |
| script will communicate with. This instance of Raid Manager |
| must be started on all the nodes before this package can |
| be successfully started. (Note: If this variable is not exported, |
| Raid Manager commands used in this script might fail). |
HORCMPERM | This variable supports the security feature, RAID Manager |
| Protection Facility on the Continuous Access devices. (Note: |
| If the RAID Manager Protection Facility is disabled, set this |
| variable to MGRNOINST. This is the default value). |
HORCTIMEOUT | (Default = 360) |
| This variable is used only in asynchronous mode when the |
| horctakeover command is issued; it is ignored in |
| synchronous mode. The value is used as the timeout value |
| in the horctakeover command, |
| value is the time to wait while horctakeover |
| the delta data from the PVOL to the SVOL. It is used for |
| |
| reached and a timeout occurs, horctakeover returns the |
| value EX_EWSTOT. The unit is seconds. |
| In asynchronous mode, when there is an Continuous Access |
| link failure, both the PVOL and SVOL sides change to a |
| PSUE state. However, this change will not take place until |
| the Continuous Access link timeout value, configured in the |
| Service Processor (SVP), has been reached. If the |
| horctakeover command is issued during this timeout |
| period, the horctakeover command will fail if its timeout |
| value is less than that of the Continuous Access link timeout. |
| Therefore, it is important to set the HORCTIMEOUT variable |
| to a value greater than the Continuous Access link timeout |
| value. The default Continuous Access link timeout value is |
| 5 minutes (300 seconds). A suggested value for |
| HORCTIMEOUT is 360 seconds. |
| During package startup, the default startup timeout value of |
| the package is set to NO_TIMEOUT in the package ASCII |
| file. However, if there is a need to set a startup timeout |
| value, then the package startup timeout value must be |
| greater than the HORCTIMEOUT value, which is greater than |
| the Continuous Access link timeout value: |
| Pkg Startup Timeout > HORCTIMEOUT > |
| Continuous Access link timeout value |
