I've got an ExtremeRaid 3000 installed in my FC3 box.
I noticed the read and write cache were disabled, so I ran the ezassist
utility and changed the cache mode from write-thru to write-back.
Now I have this configuration:
Logical Drives:
/dev/rd/c0d0: RAID-1, Online, 71131136 blocks
Logical Device Initialized, BIOS Geometry: 255/63
Stripe Size: 64KB, Segment Size: 8KB
Read Cache Disabled, Write Cache Enabled
/dev/rd/c0d1: RAID-5, Online, 100657152 blocks
Logical Device Initialized, BIOS Geometry: 255/63
Stripe Size: 64KB, Segment Size: 8KB
Read Cache Disabled, Write Cache Enabled
/dev/rd/c0d2: RAID-5, Online, 619794432 blocks
Logical Device Initialized, BIOS Geometry: 255/63
Stripe Size: 64KB, Segment Size: 8KB
Read Cache Disabled, Write Cache Enabled
No Rebuild or Consistency Check in Progress
How does one enable the read cache?
Is this a driver option or something that needs to be done at the card
level?
