Dear Colleagues,
I'm considering switching from mfi to mrsas, so a couple of questions to
those of you who use mrsas.
1. I have mirrors configured in mfi (see below). After switching, shall
I continue to see and use the configured hardware RAID volumes, or will
the disks suddenly become.. well, just separate disks?
2. I think I'll lose the convenience of mfiutil. Is there anything to
manage mrsas drives/volumes/firmware from inside FreeBSD (adding arrays,
monitoring drives etc)?
My controller:
# mfiutil show adapter
mfi0 Adapter:
Product Name: PERC H730P Adapter
Serial Number: 8A801NM
Firmware: 25.5.5.0005
RAID Levels: JBOD, RAID0, RAID1, RAID5, RAID6, RAID10, RAID50
Battery Backup: present

Maximum Stripe: 1M
# mfiutil show config
mfi0 Configuration: 2 arrays, 2 volumes, 1 spares
array 0 of 2 drives:
drive 0 ( 1118G) ONLINE <SEAGATE ST1200MM0099 ST31 serial=WFK0VDHV> SCSI-6
