Hardware Specifications and Features 3.3.2 Support for Non-Hard-Disk-Drive SCSI Devices (Non-DirectAccess Devices) The RAID controller will pass through to the host operating system direct access to nondirect-access SCSI devices which are connected to a SCSI bus (channel) of the RAID controller. The RAID controller passes through all control of these devices to the host operating system. Types of supported non-Direct-Access SCSI devices (this does not cover specific vendors and models): • SAF-TE Processors. • Tape Backups. Check with your vendor. Some manufacturers recommend that you do not connect a tape backup drive directly to a RAID controller of any kind. • CD-ROMs. 3.4 Array Roaming Compatibility Array Roaming allows the user the ability to move a complete RAID array from one computer system to another computer system and preserve the RAID configuration information and user data on that RAID array. ††Compatible RAID controllers must control the RAID subsystems of the two computer systems (see list of compatible controllers in this section). The hard disk drives are not required to have the same SCSI ID in the target system that they did in the original system that they are removed from. Note: For a migrated RAID array to be recognized by the new host operating system, the host system may need to be rebooted. Warning: †† The SRCU42L controller, with firmware 2.34.yy-Rzzz, is not compatible with the previous series of the GSU31 (SRCU31LA) controller (firmware versions 5.xx) and the previous series of the BNU31 (SRCU31A) controller (firmware versions 4.xx). Do not attempt RAID Array Drive Roaming between RAID controllers that are not compatible with the SRCU42L controller. Unpredictable behavior may include, but is not limited to, data loss or corruption. Compatible controllers include: • SRCU42L - Firmware version 2.34.yy-Rzzz • SRCU31LA - Firmware version 2.3x.yy-Rzzz • SRCU31A- Firmware version 2.3x.yy-Rzzz • SRCU32 - Firmware version 2.3x.yy-Rzzz • SRCZCR - Firmware version 2.3x.yy-Rzzz Hardware Installation and User's Guide 25

Hardware Specifications and Features
3.3.2
Support for Non-Hard-Disk-Drive SCSI Devices (Non-Direct-
Access Devices)
The RAID controller will pass through to the host operating system direct access to non-
direct-access SCSI devices which are connected to a SCSI bus (channel) of the RAID
controller. The RAID controller passes through all control of these devices to the host
operating system.
Types of supported non-Direct-Access SCSI devices (this does not cover specific vendors
and models):
•
SAF-TE Processors.
•
Tape Backups. Check with your vendor. Some manufacturers recommend that you do
not connect a tape backup drive directly to a RAID controller of any kind.
•
CD-ROMs.

Array Roaming Compatibility
Array Roaming allows the user the ability to move a complete RAID array from one
computer system to another computer system and preserve the RAID configuration
information and user data on that RAID array. ††Compatible RAID controllers must
control the RAID subsystems of the two computer systems (see list of compatible
controllers in this section). The hard disk drives are not required to have the same SCSI ID
in the target system that they did in the original system that they are removed from.
Note:
For a migrated RAID array to be recognized by the new host operating system, the host
system may need to be rebooted.
Warning:
††
The SRCU42L controller, with firmware 2.34.yy-Rzzz, is not compatible with the
previous series of the GSU31 (SRCU31LA) controller (firmware versions 5.xx) and
the previous series of the BNU31 (SRCU31A) controller (firmware versions 4.xx). Do
not attempt RAID Array Drive Roaming between RAID controllers that are not
compatible with the SRCU42L controller. Unpredictable behavior may include, but
is not limited to, data loss or corruption.
Compatible controllers include:
•
SRCU42L – Firmware version 2.34.yy-Rzzz
•
SRCU31LA - Firmware version 2.3x.yy-Rzzz
•
SRCU31A– Firmware version 2.3x.yy-Rzzz
•
SRCU32 – Firmware version 2.3x.yy-Rzzz
•
SRCZCR – Firmware version 2.3x.yy-Rzzz
