From e555db930f7512491485cfc43df4306192835373 Mon Sep 17 00:00:00 2001 From: Brian King Date: Thu, 19 Apr 2007 13:59:59 -0500 Subject: [PATCH] [SCSI] use sysfs configured timeout for EH Start Unit timeout Use the sysfs configurable timeout when issuing a START_UNIT command from the scsi error handler. This is needed for devices which take longer than thirty seconds to respond to the start unit. The problem was observed when sending a start unit to a disk array device in an ipr RAID adapter, which results in the adapter firmware sending potentially multiple commands to physical devices as a result of this command, which ended up timing out sometimes. This patch does not change the default value used for this command.
