5.1 Steps to Install

5.1.2 Where to Install the SF7x Storage Enclosure

The SF7x storage enclosures install in numerical order. Refer to Chapter 3.

SF7x storage enclosures could occupy positions 1, 2, 3, 4, 5, and 6 .

In split-bus mode, the following drives are part of the same DSSI bus (note

that split-bus mode is supported in the single-host conﬁguration only):

1. Four drives of SF1 with the two left drives SF3

2. Four drives of SF2 with the two right drives SF3

3. Four drives of SF4 with the two left drives of SF6

4. Four drives of SF5 with the two right drives of SF6

Note

In a stripeset conﬁguration, all SF7x storage enclosures must be in

split-bus mode. Each DSSI bus is connected to two ISEs in each SF7x

enclosure. One KFMSA module is required for each SF7x storage

enclosure.

All SF7x storage enclosures must be in through-bus mode when the Sx300

storage array is in the dual-host conﬁguration:

1. Four drives of SF1

2. Four drives of SF2

3. Four drives of SF3

4. Four drives of SF4

5. Four drives of SF5

6. Four drives of SF6

5.1.3 Checking the System Conﬁguration Sheet

Locate the system conﬁguration sheet. If you cannot locate this sheet or if the

one that is available is either not ﬁlled out or ﬁlled out incorrectly, ﬁll one out

immediately.

Refer to the KFMSA Module Installation and User Manual (EK–KFMSA–IM)

for an explanation of this sheet and how to ﬁll it out.
