System: Digital Alpha 8400 running Digital Unix 3.2e
This is a new system, and we're still in the process of setting it up and
configuring it. The system disk is mirrored using LSM, and both the system
disk and mirror disk are internal disks.
Can anyone advise what we can expect if we take a disk hit (boot disk
crashes while we're running)? The documentation is a bit vague in that it
indicates we will "be able to" reboot from the mirror, which we assumed,
but does not specify that we will have no other options EXCEPT to reboot
from the mirror.
As a sort of pseudo-test, we tried physically removing the system disk
while the system was running, but idle (root logged on, no applications
running, no users accessing anything). The system continued to function,
but somewhat slowly. Once the system disk was returned to the box,
everything went back to normal. Obviously, this was not a true test. We
want to set our expectations to the reasonable rather than the improbable,
so can anyone tell us whether we will absolutely need to completely reboot
the system from the mirror, or will it be transparent to us? Will rebooting
from the mirror eliminate the sluggishness we observed? Does anyone have
any experiences/advice to share?
Thanks in advance for any help.
... Al
