Explanation
A VARY ONLINE command requested that a device or
a console be varied online, but there are no paths of the indicated
type, logical or physical, available for this device or console, or
the device is not in a ready state.
In the message text:
- dev
- The device number of the device to be varied online.
- nnnnnnnn
- The name of the console to be varied online.
Multiple console
support (MCS) treats the specified console as if it were a 3277 Display
Station (Model 2).
- LOGICAL
- There were no logical paths available for the device or console.
- PHYSICAL
- There were no physical paths available for the device or console.
- UNCOND ACCEPTED
- The device was brought online even though it may have no logical
or physical paths to it.
System action
The system rejects the command.
Operator response
Depending on the message text, do the following:
- LOGICAL
- Issue a VARY PATH(dddd,cc),ONLINE in order to bring both a path
and the device online.
If the device is not a tape or a direct access
storage device (DASD) and you cannot bring the device online, but
a critical job requires that the device be online, enter the VARY
ONLINE command again for the device specifying the UNCOND parameter.
The device will be marked online even though a path for it does not
exist and the device cannot be used for I/O operations. Check all
logical paths to the device.
- PHYSICAL
- At system initialization, check the system log (SYSLOG) for messages
related to hardware problems. Contact hardware support, providing
the messages.
