What is epoch time?


The Unix epoch (or Unix time or POSIX time or Unix timestamp) is the number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds (in ISO 8601: 1970-01-01T00:00:00Z).

Literally speaking the epoch is Unix time 0 (midnight 1-1-1970), but 'epoch' is often used as a synonym for 'Unix time'.   Many Unix systems store epoch dates as a signed 32-bit integer, which might cause problems on January 19, 2038 (known as the Year 2038 problem or Y2038).

Random TIPS

Removing "Drive Not Available" from Solaris

These are steps I followed to remove the LUNS which were unmasked from the system.
Removing the Unused/Unmasked LUNS from Solaris.

1. First Step is identifying the from Format o/p.
2. Remove them from Volume Manager. In my case, they are veritas. so I used vxdisk rm
3. look at the cfgadm -al o/p to find the disks which are failing. they are failing because they are unmasked from this system and still OS sees them.
c3::50060482d53135b8,84 disk connected configured failing
c3::50060482d53135b8,86 disk connected configured failing
c3::50060482d53135b8,87 disk connected configured failing
3. luxadm -e offline /dev/rdsk/ # This will kick the device from failing to unusable. and also removes them from format o/p.
4. cfgadm -o unusable_FCP_dev -c unconfigure c3::50060482d53135b8
# This will remove all unusable LUNS from system for particular controller and target id. don't worry there might be some working devices on that target. This command won't affect them. they'll be in working state only.
5. clean the device files using devfsadm -Cv
6. You should be clear now in both format and cfgadm -al.
