Problem IC76723
|
Status: Closed |
PURESCALE INSTALLER ON AIX DOES NOT SET UP RESERVE_POLICY OR ALGORITHM OF TIE-BREAKER DISK FOR REMOTE HOSTS. |
| product: |
DB2 FOR LUW / DB2FORLUW / 980 - DB2 |
| Problem description: |
The pureScale installer changes reserve_policy and algorithm of
tie-breaker disk on installation-initiating host (IIH), but
installer does not change the attributes on the other hosts in
the cluster. The attributes should be set as same on all hosts.
On IIH:
# lsattr -El hdiskx | egrep "reserve_policy|algorithm"
algorithm fail_over Algorithm True
reserve_policy single_path Reserve Policy True
On the other cluster hosts.
# lsattr -El hdiskx | egrep "reserve_policy|algorithm"
algorithm load_balance Algorithm True
reserve_policy no_reserve Reserve Policy True
where hdiskx is tiebreaker disk. |

| Local Fix: |
Please update the attributes on the other hosts manually by
chdev command like as below:
/usr/sbin/chdev -l hdiskx -a algorithm=fail_over
/usr/sbin/chdev -l hdiskx -a reserve_policy=single_path |
