It has been some time since we updated our PURE FlashArray configuration. The
Linux vendors that we had been seeing in the field were using very old versions
of multipath-tools, so we haven’t needed to change anything for some time. With
the release of RHEL8, some of our earlier values have been lost by upstream
changes.
Resend it, with CC: Christophe Varoqui <christophe.varoqui@xxxxxxxxxxx>
In addition we have our Active Cluster feature which leverages ALUA since our
last patch. The ALUA confguration will work for all FlashArrays with or without
Active Cluster.
We are changing 3 things.
1. ALUA support
2. Fast fail timeout from the default of 5 seconds to 10 seconds (We need this
for our FC NPIV port migration).
3. Maximum sector size of 4MB. Some Linux vendors don’t honor the block limits
