Table: scsimgr Attributes
This table lists the
scsimgr generic attributes and some "Device Set" attributes. Under the category
"Device Set" attributes, the table lists which attributes the
esctl driver allows at a settable attribute
scope (also known as Device Data Repository, DDR). Attributes scopes supported by
esctl are peri-
pheral device type (pdt) of 0xC, vendor identifier (vid), product identifier (pid), and product revision (rev).
See attr_scope for more information
Note: In this attribute description table, the following conventions are used:
•
RO is Read Only.
• RW is Read Write.
• Range of values for applicable attributes is listed.
Object Attribute Name RO/RW Type Description
Global version RO string Version of SCSI services
Max value of lunid to probe for
devices which do not support
REPORT LUNS command.

max_lunid RW uint32
Seconds to wait after a LUN has
gone OFFLINE before failing I/Os
transient_secs RO uint32
Number of LUNs discovered on
the host
lun_cnt RO uint32
Number of SCSI HBA controllers

ctlr_cnt RO uint32
Debug level used to filter diagnos-
tic messages logged.
Range:
0 (lvl_panic ) System unusable
1 (lvl_alert ) Immediate action
required
2 (lvl_critical ) Critical condi-
tion

Default setting of tunable to
enable or disable multi-pathing
on legacy DSF of a LUN.
Values: false (0) or true (1).
leg_mpath_enable RW boolean
Maximum I/O size allowed by the
SCSI subsystem in 4KB units.
Range: 64 - 1048575
escsi_maxphys RW uint32
