Explanation
reason is one of the following:
- ASSIGNED TO ANOTHER SYSTEM
- ASSIGN CONFLICTS WITH CURRENT DEVICE STATUS
- ASSIGN FAILED, RC =rc
- DYNAMIC PATHING NOT OPERATIONAL ON DEVICE
A VARY ONLINE command requested dynamic pathing for a
device. The command failed.
In the message text:
- dev
- The device number for which the VARY command requested dynamic
pathing.
- ASSIGNED TO ANOTHER SYSTEM
- VARY ONLINE was entered, but the device is assigned to another
system. This system cannot have exclusive access to the device. If
the device is shared by another system, it is possible for this system
to get shared access.
- ASSIGN CONFLICTS WITH CURRENT DEVICE STATUS
- Either:
- A VARY ONLINE command specified a device that is already assigned
to this system. The requested assign status conflicts with the current
device status. A single-system assign request cannot be honored if
the device is already assigned with shared status.
- A VARY ONLINE,SHR command specified a device that is autoswitched.
The command is rejected because SHR is incompatible with automatic
tape switching.
- ASSIGN FAILED, RC =rc
- A VARY ONLINE command failed. rc is one of
the following:
- 16
- A time out occurred while the system was performing I/O to assign
the device.
- 20
- A permanent I/O error occurred while the system was performing
I/O to assign the device, or the device is currently forced offline
(boxed).
- 28
- A SENSE operation failed while the system was performing I/O to
assign the device.
- DYNAMIC PATHING NOT OPERATIONAL ON DEVICE
- A VARY ONLINE command attempted to establish dynamic pathing for
a device. The path group was not established.
System action
The system ends VARY ONLINE processing for the
specified device. The system does not change the device status.
Operator response
Depending on the message text, do the following:
- ASSIGNED TO ANOTHER SYSTEM
- If a single-system request was made, choose another device to
vary online. If the device is required, vary the device offline to
the other system, then vary it online to this system. If a shared
request was made, but some other system has the device exclusively,
choose another device to vary online with the SHR option. If the device
is required, vary the device offline, or online shared, to the other
system, then vary it online with SHR to this system.
Note: The VARY
command must be entered from a console attached to the system it is
meant to affect.
- ASSIGN CONFLICTS WITH CURRENT DEVICE STATUS
- Either:
- A VARY ONLINE command specified a device that is already assigned
to this system. The requested assign status conflicts with the current
device status. A single-system assign request cannot be honored if
the device is already assigned with shared status.
VARY the device
offline, then back online.
- A VARY ONLINE,SHR command specified a device that is autoswitched.
The command is rejected because SHR is incompatible with automatic
tape switching.
VARY the device to be not autoswitchable, then
issue the VARY ONLINE,SHR command.
- ASSIGN FAILED, RC=rc
- Enter the VARY command for the device again. If the command fails
again, the device or control unit could be malfunctioning, which would
prevent the device-end or control unit end from being received. Contact
hardware support.
System programmer response
Do the following:
- If dynamic pathing is not operational on the device and if the
logrec data set contains hardware error records for the device, contact
hardware support.
- If the logrec data set OBR-DPA record contains incorrect path
group ID information, search problem reporting data bases for a fix
for the problem. If no fix exists, contact the IBM® Support
Center.
