I have a little issue that doesn't really disturb day-to-day usage but is quite annoying for those who monitor the systems.
Every day around 16.00 gmt+1 I get between 4-10 errors in my dsa0:[sys0.sysmgr]operator.log saying that a bunch of disks are offline. This just happens once for each disk and then directly after it says mount completed and then mount verification is in progress (see the attached snipped log). Everytime this happens the disks report +1 on their error counts so in our PSW it shows up as an high priority error.
Is this something anyone has seen before?
The machines in question is clustered with a joint connected SAN and they both run OpenVMS 7.3-2

Re: Mount verification problem
If you want further analyze these mount-verifications and trying to find the underlying reason, concentrate on all components in the IO path to the disks.
Thanks.

Re: Mount verification problem
First, it is a Compaq Storageworks Raid Array atleast. How do you easily check what the battery state is? and where is this battery located?
Second, This does not occur a couple of times a month. It occours daily and around 16.00. I've talked to our datacenter guys and they say they are'nt doing anything around these hours or with these machines.
I've tried to find consistencys to the pattern when this is reoccuring but the diffrence is varying too much. Some days it's pushed forward by about 25s/per disk/per error and some times more or less.
The only thing really reoccuring event is that it's coming back every day around 16.00.
There is not batchjobs running around that time and i can't seem to find any process doing anything special either.
I've concluded a while back that these errors are harmless, but as i said it's an annoyance for our monitoring group since they show up all the time.
I'll attach my statistics file which I totaled the amounts of errors/per day and how many seconds this particular device reported an error compared to the day before.

Re: Mount verification problem
When I run set host/scsi it asks me for a device and when I've supplied that it just returns "error activating image HSZTERM$SCSIPAD" and "Image file not found $1$DKA0:[SYS0.SYSCOMMON.][SYSEXE]HSZTERM$SCSIPAD.EXE;"
Am i giving it the wrong device name?
I found a "console template" named hsz10 so I was assuming that it's the name for the device?
Sorry if I'm not doing everything right, I'm quite the newbie at OpenVMS system management.

Re: Mount verification problem
RUN FMU
FMU> SHOW LAST_FAILURE MOST_RECENT
If you have a FC connected array you need different software.
Purely Personal Opinion

Re: Mount verification problem
Got the terminal to work against my StorageWork RA and it said what I wanted.
Cache battery is near its end of life, it should be replaced SOON. Run frutil-
to replace.
Mirror cache battery is near its end of life, it should be replaced SOON. Run-
frutil to replace.
This should be easily solved by just replacing the batteries :)

Re: Mount verification problem
I had a HP guy here that helped me change the batteries in my esa10000/RA8000 (found out that hsz80 is just the controller for the unit).
Anyway, thank you all for the help and the suggestions :)
