There are 12 Solaris hosts connected to two fabrics and a DMX2000. All the hosts are dual-pathed
using Emulex HBAs. All 12 HBAs in each fabric are connected and zoned to one FA port. Each
host is doing 2000 IOPS. Each I/O size is 64KB. Two of the hosts are receiving the following error
in their /var/adm/messages file: SCSI transport failed: reason ‘timeout’: retrying command What do
you advise the customer to do?

A.
Increase the queue depth of the HBAs reporting the SCSI retry messages in
/kernel/drv/lpfc.conf file

B.
Reduce the queue depth of the HBAs reporting the SCSI retry messages in /kernel/drv/lpfc.conf
file

C.
Reduce the queue depth of the HBA reporting the SCSI retry messages in /kernel/drv/sd.conf
file

D.
Use Unix command sysdef queue_depth command to increase the queue_depth
