Fixes

• Cache management — Improves cache management to prevent I/O errors in the following

situations:

• During a LUN failover while the MSA controller is performing RAID migration or expansion

under a heavy load

• Preventing persistent host I/Os from bypassing cache when cache is dirty on powerup

• Preventing I/O timeouts in cases where many implicit failover events occur within a short

period of time

• Default profile — With version 7.00 of the firmware, the default profile loads the correct host

mode settings after upgrading from an earlier release of firmware. This was not the case when

upgrading to version 6.86 from an earlier version; in this situation, the default profile m ight

not have loaded the correct host mode settings when assigned to a host connection. Any host

connectionthatwasleftsetto“Default”andnotsettothecorrecthostmodeprofile,suchas

Windows or Linux, would fail to load support software, such as the ACU, event notification

driver, or multi-path software.
