7.2
Generation of the ETERNUS DX8700 S3 on the SE Server
(SU /390) and S-Server
The ETERNUS DX8700 S3 is generated in the same way as any other disk subsystem connection via FC. D3435
(internal type A5) must be specified as disk type.
The generation is explained using the previously configured ETERNUS DX8700 S3 as an example.
The LUN group LG01 can be viewed as a logical controller with 80 devices on 4 FC channels. 2 PAV alias devices
are generated for each LUN. This permits 3 parallel input/outputs per volume. Without PAV alias devices, it
would only be possible to execute 1 input/output per volume at the same time.
240 devices (80 LUNs + 2 x 80 PAV alias devices) are thus generated per logical controller, 16 device addresses
remain spare.
Excerpts for IOGEN instructions for the SE700 Server with ETERNUS DX8700 S3 are listed below.
■
Generation instructions for FC channels
1 channel is generated for each SE700 Server FC channel:
CHN 4A,IBF,A,MODE=FCP
CHN 47,IBF,A,MODE=FCP
CHN 0D,IBF,A,MODE=FCP
CHN 04,IBF,A,MODE=FCP
■
Generation instructions for controllers
2 controllers (MN=26xx) are generated for each ETERNUS DX8700 S3 FC port and SE Server FC channel:
CTL 2600,BLM,A,(4A,0,500000E0DAC19A00),(0D,0,500000E0DAC19AC5) *FABRIC1/2
CTL 2601,BLM,A,(47,0,500000E0DAC19A15),(04,0,500000E0DAC19A10) *FABRIC1/2
■
Generation instructions for devices
For the 80 logical volumes in LUN group LG01 of the ETERNUS DX8700 S3, 80 devices (subchannels) are
generated with MNs from 2600 to 264F and with host LUN numbers from 0x00 to 0x4F:
DVC 2600,A5,D,0000,(2600),(2601),MULT=80
For the same 80 logical volumes, 80 PAV alias devices are generated with MNs from 2650 to 269F and with
PAV addresses from 0x50 to 0x9F:
DVC 2650,A5,D,0000,(2600),(2601),MULT=80,PAV=50
For the same 80 logical volumes, another 80 PAV alias devices are generated with MNs from 26A0 to 26EF and
with PAV addresses from 0xA0 to 0xEF:
DVC 26A0,A5,D,0000,(2600),(2601),MULT=80,PAV=A0
The address range from 0xF0 to 0xFF remains unused.
