Hello,
I have a sparc S10 system - Solaris 10 6/06 s10s_u2wos_09a SPARC with
QLA3242 HBA, driver version - qla-5.01. I have a Tagmastore array
(USP100) connected to a SAN with volumes mapped to this Solaris host. I
have Veritas Storage Foundation 4.1 installed on this system for
multipath software.
I have been searching through docs to find out if I have to set any SCSI
tunable parameters like sd_io_time and sd_retry_count for failover
purposes. I am running some tests and when the storage port on the
switch is disabled, I see from the console on the host the following
messages :
Nov 13 10:34:10 apps-223 scsi: [ID 107833 kern.warning] WARNING:

/tag_fs is my file system striped across tagmastore disks , tag_dg is my

Any help on this is greatly appreciated.
