RA8000/ESA12000 HSG80 Solution Software V8.5 for Sun Solaris
Page 14 387372-005 AA–RFBPE–TE
However, the HSG80 controller, and Solaris, can support up to 64 LUNs per
port/Target. If your environment requires more than 16 LUNS/Target, you may
perform the following work-around, keeping the following notes in mind:
NOTE
• You should be running Solaris 2.6 or
Solaris 2.7 with the required patches
installed.
• You may need to adjust the
ad_max_throttle setting in
/etc/system (see Section 7.11 below)
• SWCC has not been tested, and is not
supported with more than 32 LUNs.
• Refer to the driver.conf (4) and sd (7D)
man pages for more information.
1. Run config.sh and choose Option 20; Add change adapters.
2. Chose Option 4; Modify and adapter.
3. Select the adapter that you want to modify.
4. Follow the instructions to modify the number of LUNs/Target. NOTE: Do
not enter more than 64.
5. Create your LUNs on the HSG80 controller. Remember that units 0–99 will
appear on port 1 (al_pa=72, target=64), and units 100–199 will appear on
port 2 (al_pa=71, target=65).
6. Shut down and do a reconfigure boot (boot -r), and your new units should be
ready for formatting.
7.11 sd_max_throttle setting in /etc/system
Solaris defaults to a queue depth of 256 tagged commands per LUN, but it only
recognizes LUN 0 on each target. The StorageWorks RAID Manager software
adds support for 16 LUNs per target, but Solaris will still allow 256 queued
commands per lun. With 32 luns mounted, you can have over 8000 outstanding
queued requests, but the controller will only support 256 queued commands per
port.
