Based on my loooong day yesterday doing my defrag re-install, here is an
updated checklist the for procedure I'll be using in the future:
MPE/iX Re-Install Procedure
___ :XEQ SHUTDOWN.PUB.CCCD from OPERATOR.SYS
___ :STREAM BACKSLT.OPERATOR.SYS (twice if paranoid)
___ :XEQ CHECKSLT.MPEXL.TELESUP for each SLT backup created above.
___ :STREAM BACKUP.INSTALL.CCCD (twice if paranoid)
Which does in part:
! CONTINUE
! DEVCTRL.MPEXL.TELESUP 7,DISABLE,ENABLE
! CONTINUE
! DEVCTRL.MPEXL.TELESUP 8,DISABLE,ENABLE
! CONTINUE
! STORE ^INDSTORE;;STORESET=(*FULLSET1),(*FULLSET2);&
! ONVS=MPEXL_SYSTEM_VOLUME_SET,CCCD_MIRROR,CCCD_JUNK;&
! DIRECTORY;INTER;SHOW=LONG;PROGRESS=5;MAXTAPEBUF;ONLINE;STATISTICS;&
! COMPRESS=HIGH
My normal system backups are online backups (concurrent batch activity occurs)
done with DDS-2 hardware compression only (i.e. no COMPRESS=HIGH).
I did some benchmarks prior to the re-install day, and discovered that
COMPRESS=HIGH *without* hardware compression results in a substantial 33%
backup runtime decrease. This improvement comes at the expense of a 30-50%
CPU load on my 969KS200, so I don't think I'll switch all of my full backups
to this method because it would slow batch production.
INDSTORE is ordered so that important files appear at the front of the backup
so they may be restored quickly:
@.INSTALL.CCCD
@.UDC.CCCD
COMMAND.PUB.SYS
EDITOR.PUB.SYS
@.PUB.SYS-COMMAND.PUB.SYS-EDITOR.PUB.SYS
@[log in to unmask]@.PUB.SYS
@[log in to unmask]@[log in to unmask]@[log in to unmask]@.SYS
___ :STREAM VERIFY.INSTALL.CCCD for each full backup created above.
Which does in part:
!VSTORE ;@[log in to unmask]@;SHOW=LONG;ONERR=QUIT;RESTORESET=(*SET1),(*SET2);&
! NODECOMPRESS;PROGRESS=5
I've never had logical corruption on a store tape, so there's no need to
decompress the data. I'm just interested in media readability.
___ =SHUTDOWN
___ ISL INSTALL from the SLT tape created by BACKSLT.
___ :HELLO MANAGER.SYS,PUB
___ :VSCLOSE CCCD_MIRROR and CCCD_JUNK non-system volume sets
___ :RESTORE *T;CCCDVOLS.INSTALL.CCCD,@.PUB.SYS;SHOW;LOCAL;KEEP;OLDDATE;DEV=1
___ :XEQ VOLUTIL.PUB.SYS "USE CCCDVOLS" to recreate volume set configuration.
CCCDVOLS was created by my BULDVOL script; I manually inserted a bunch of
scratchvol commands. BULDVOL successfully determined my full configuration,
which was recreated successfully by VOLUTIL.
___ :RESTORE *T;;DIRECTORY;SHOW;OLDDATE
Here something weird happened:
/SYS/PUB/public_html COULD NOT BE RESTRICTED TO THE SYSTEM MASTER VOLUME
/SYS/hpstage ditto
/SYS/hpstage/MPEKX56A ditto
/SYS/hpstage/base-archive ditto
/SYS/hpstage/export ditto
/SYS/hpstage/import ditto
Not a big deal; I ended up purging public_html, and the stage stuff can be
recreated via STAGEMAN.
But still weird. Does anybody have an explanation?
___ :RESTORE *T;@.INSTALL.CCCD,@.UDC.CCCD;SHOW;OLDDATE
___ :STREAMS 10
___ :OPENQ LP
___ :STREAM RESTJOB.INSTALL.CCCD
Which does in part:
!RESTORE ;@[log in to unmask]@;RESTORESET=(*SET1),(*SET2);&
! SHOW=LONG;CREATE;KEEP;OLDDATE;ONERR=SKIP;PROGRESS=5
___ Manually deal with files that had creator problems.
___ =SHUTDOWN
___ ISL START NORECOVERY
