HSD10 Operation
VAX 4000 Model 108 User Information 4-25
7. At the verification prompt, check that the device name given under the Device header
of the TAPETEST display is the device that you need to exercise. Answer "Y" or
"YES" to begin the device exercise.
8. Enter the ABORT command to terminate the TAPETEST operation.
9. Enter the DESELECT command to bring the device back to the AVAILABLE status.
10. Enter the appropriate operating system commands to bring the device on line.
Transporting Drives to/from the HSD10 Environment
Nonstriped, nonpartitioned disk drives written while configured on the HSD10 adapter
may be physically transported directly to the environments listed below if they are
identified as DIAx devices (as a result of the HSD10 DEVICE_TYPE parameter set to 'HS'
or 'RF'):
•
HSD30[TM], HSJ40[TM], or HSC controllers (equipped with K.scsi modules), and
with drives mounted in `DK' mode
•
Other native SCSI adapters
Nonstriped, nonpartitioned drives also can be read and written interchangeably between
the HSD10 and HSD05 adapters, as long as the equivalent DEVICE_TYPE parameter
settings match.
No other direct media transportability is supported to/from the HSD10 and other
environments. Data transportability also can be accomplished by transferring files over the
local network or to another transportable medium such as tape.
Drives attached to the HSD10 may not be warm swapped.
Shadowing Restrictions
The HSD10 adapter uses a limited set of disk device type identification names when
communicating with the host. All attached disk drives by default are identified as HSX00.
This identifier can be changed to RA82[TM] or RF72[TM] by setting an HSD10
parameter, DEVICE_TYPE, as described in Table 4-5 and the StorageWorks Solutions
HSD10 Array Controller User’s Guide, EK-HSD10-UG, under the SET CONTROLLER
command. The device type reported to the host does not affect actual accessible disk
storage space.
The HSD10 adapter supports host-based volume shadowing (host-based RAID 1).
Shadowing requires that members of a shadow set have identical device identifiers and
disk capacities. Although disk drives on the HSD10 adapter may be identified as RF72,
