Solution  1003181.1 :   Sun StorEdge[TM] A1000/RSM2000/Sonoma: Problem getting 16 lun support to work on PCI based systems  


PreviouslyPublishedAs
204367

Symptoms
Problem getting 16/32 lun support to work on PCI based systems.
( Sun Enterprise[TM] 450 with Sun StorEdge[TM] A1000 ).
Followed the 16 lun "cookbook" instructions and script "add16lun.sh".
After booting, only 8 luns are recognized.

Resolution

There may be an incorrect glm.conf entry or a missing glm.conf file.
If the customer is trying to configure greater then 8 LUNS on a  PCI  based system they must create or edit the  /kernel/drv/glm.conf  file to include the entries below.
Use the following example to enable 16/32 lun support on PCI based systems
(E250/450) with A1000/RSM2000/Sonoma:
glm.conf for Solaris 2.6
device-type-scsi-options-list =
"Symbios StorEDGE A1000", "lsi-scsi-options",
"Symbios StorEDGE A3000", "lsi-scsi-options",
"SYMBIOS RSM Array 2000", "lsi-scsi-options";
lsi-scsi-options = 0x107f8;
glm.conf for Solaris 7, Solaris 8 or Solaris 9
device-type-scsi-options-list =
"Symbios StorEDGE A1000", "lsi-scsi-options",
"Symbios StorEDGE A3000", "lsi-scsi-options",
"SYMBIOS RSM Array 2000", "lsi-scsi-options";
lsi-scsi-options = 0x407f8;
Solaris 7 also needs patch 106925-05 or later for 16 LUN support.

extract from /usr/include/sys/scsi/conf/autoconf.h

/*
* the following 3 bits are for being able to limit the max. number of LUNs
* a nexus driver will allow -- "default" means that the adapter will
* continue its default behaviour
*/
#define SCSI_OPTIONS_NLUNS_MASK (0x70000)

#define SCSI_OPTIONS_NLUNS_DEFAULT 0x00000
#define SCSI_OPTIONS_NLUNS_1 0x10000
#define SCSI_OPTIONS_NLUNS_8 0x20000
#define SCSI_OPTIONS_NLUNS_16 0x30000
#define SCSI_OPTIONS_NLUNS_32 0x40000

Be aware that there is a conflict between Solaris 6 and Solaris 9.
The 16/32 LUN option setting for solaris 6 - 0x107f8 - will only allow one LUN in solaris 9.
