subsidiary logical unit (SLU)
An LU used for the conglomerate LUN structure, a SCSI architecture
model. An SLU is an LU that stores actual data. You can use a DP-VOL or
snapshot data (or a V-VOL allocated to snapshot data) as an SLU. All host
access to SLUs is through the administrative logical unit (ALU). An SLU is
called a virtual volume (VVol) in vSphere. See administrative logical unit.

T10 PI
See T10 Protection Information.
T10 Protection Information (T10 PI)
A code standard defined in SCSI. T10 PI adds 8-byte protection
information at every 512 bytes to validate data. By combining T10 PI with
Data Integrity Extension (DIX), which enables data protection covering
application and operating system, data protection from application to disk
drives can be provided.
target volume (T-VOL)
The volume in a mainframe copy pair that is the copy of the original data
on the source volume (S-VOL). The term is used only in the earlier
version of the Device Manager - Storage Navigator GUI (still in use), for
the following Hitachi products: ShadowImage for Mainframe, Dataset
Replication, and Compatible FlashCopy
