I'm unable to offline device/drive using vary offline. The message was PENDING OFFLINE AND BOXED. When I displayed the device, it shows O-BOX.
How to bring this offline without IPL the system?

Un-BOX the device, then it can be brought offline.

To un-BOX the device, you need to figure out why it is boxed. From the IBM documentation at https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.3.0/com.ibm.zos.v2r3.ieag100/iea3g1_Device_boxing.htm:
Quote:
The system boxes a device:

When it detects hot I/O on the device and the device cannot be recovered
When, because of a channel path error, it takes the last path to the device offline
When, because of a channel path error, it releases a reserve or assign on the device
When it releases an unconditional reserve for the device
When you issue a VARY OFFLINE command with the FORCE option for the device
When you issue a CONFIG OFFLINE command with the FORCE option for a channel path, and the command releases a hardware reserve or assign, or removes the last path to the device
