2. Reboot the system.
ZFS root pool Requires Maintenance After Every
Reboot (6856341)
After reboot the ZFS root pool comes up in degraded mode. A mirrored root pool that might be
impacted by this issue will contain disk devices that use dierent device drivers and the second
driver isn't loaded during the boot process.
A symptom of this issue is when the system is rebooted, the pool state is DEGRADED because
both device drivers are not loaded at the same time. A mirrored root pool that might be
impacted by this issue will have zpool status output similar to the following:
state: DEGRADED
status: One or more devices could not be opened. Sufficient replicas exist for
the pool to continue functioning in a degraded state.
Workaround: Perform the following steps:
1. Identify the device drivers to be force loaded. For example, use the prtconf command with
syntax similar to the following:
# prtconf -aD /dev/rdsk/c1t0d0
SUNW,Sun-Fire-280R (driver name: rootnex)
pci, instance #1 (driver name: pcisch)
SUNW,qlc, instance #4 (driver name: qlc)
fp, instance #5 (driver name: fp)
ssd, instance #5 (driver name: ssd)
2. Edit the /etc/system le and provide a forceload entry for each driver identied in step 1.
For example:
forceload: drv/qlc
forceload: drv/ssd
forceload: drv/fp
