Solaris 10 Zone Survival Guide by Robert Chase           Original from: http://www.systemv.org/downloads.html Solaris Zones are a lightweight virtual machine product for the Solaris 10 operating system. You may also see zones referred to as Solaris containers.  Older versions of Solaris do not support zones however the zone’s themselves can run older versions of Solaris in addition to Linux. Zones present a number of interesting and new challenges to a Systems Administrator.  For example the machine you have an issue with may be a real machine on physical hardware or a zone.  Knowing the difference can assist you in in making decisions on how to solve the problems you are presented with.  While you may be aware of the user impact of the main machine the system could be running a number of Zones which broaden the user impact regarding decisions that you might make to solve […]

Solaris and Netbackup, Issues with the bpcd process Very often I run into the issue that the bpcd process is getting hung or having similar issues. Errors might be like: # netstat -a |grep -i bpcd reports CLOSE_WAIT bpcd is not responding One Solution is to restart the process: Solaris up to 9: restart by using # /etc/init.d/inetsvc stop; /etc/init.d/inetsvc start to restart the full inetd process make sure you use the full line else you might drop the network. Solaris 10: # svcs -a |grep bpcd to see the process and state. # svcadm restart svc:/network/inetd:default           to restart the demon # svcadm restart svc:/network/bpcd/tcp:default  to restart the demon if its in maintence mode after those commands: # svcs |grep bpcd maintenance    10:28:52 svc:/network/bpcd/tcp:default Then use # svcadm clear svc:/network/bpcd/tcp:default # svcs |grep bpcd       shall report online          9:25:05 svc:/network/bpcd/tcp:default reference:    http://seer.entsupport.symantec.com/docs/256685.htm Sometimes it happens that bpcd appears to be ‘listening’ […]
